Between this expose on Arben K and his history of stealing the code of others and selling it illegally (Arben is the "developer" of CherryOS though he has changed his story and now claims that he was merely the "visionary" behind it, not the programmer -- rather unbelievable since there are records of him posting about elementary PHP questions on various newgroups)... to today's article in Wired News which includes these choice quotations (see below)... there's very little room to doubt:

- CherryOS *does* exist in the sense that you can download a program called CherryOS that attempts to make it possible to run OS X on an x86 machine

- However CherryOS is a rip/copy of PearPC, straight from its GPL source. This is a very illegal violoation of PearPC's GPL license because CherryOS is neither crediting PearPC nor "giving back" to PearPC the code that they may have changed or added. Since CherryOS is a rip of PearPC, it will NOT deliver on the 80% performance promised, and in fact, it even lacks some of the features that newer builds of PearPC have (native CD-ROM on Windows, sound, etc).

Dave Schroeder, senior systems engineer at the University of Wisconsin, examined a pre-release copy of CherryOS downloaded from Maui X-Stream by Wired News. Schroeder concluded CherryOS is likely PearPC wrapped in a different package.

Schroeder said he compared the names of various functions and variables in CherryOS and PearPC, and found they all matched.

"This is pretty clear-cut," he said. "They are, in fact, using significant amounts of code from PearPC."

The software does include functions of starting and stopping the emulator, and support for multiple profiles, but the implementation is rough and incomplete, he said.

Sebastian Ballas, PearPC's lead developer, said a screenshot of CherryOS shows a variable named "SPIRO MULTIMAX 3000," a nonsensical term Ballas claims to have invented for use in PearPC.

"It is absolutely unlikely that someone uses exactly this name for the same purpose," he said. "The way he (Kryeziu) is lying is making me angry."

Story over.

Ok guys, i need some help here. I am new to running Pearpc so I used the program PearPC Control Panel to create a config file and to get PearPC up and running. It seems to be working alright untill a gray screen with the apple logo appears with a spinning circle and this one line keeps repeating in the log window. Any ideas?

Hehe... take your pick of OS... running on my dual monitors.

Show off! I guess this means OSX is really runnable in an x86 environment.. Now the next question, is it usable?

Well I must say.. Despite it reporting 9XXmhz and 256megs of ram it was still more than I expected.. I suppose some day people won't need different boxes for Mac and Windows dual booting, the way this is going. Especially since I can see how, with the proper high-end wallet spanking hardware, you could use it somewhat effectively as it stands. Just my two cents.. And here's your change.

OKAYZ! I successfully converted my .dmg files to .iso files. Done and Done! PM me if you wanna know how.

I made a copy of the ppccfg.example file, edited it (directed it to a hd image (downloaded 3gib image from pearpc): replaced "test/imgs/linux.img" from the example with "pearpc-3gib.img" [it is in the pearpc directory], and directed it to a cd image: replaced "/dev/cdrom" in the example with "osxcd1.iso").

When i ran cmd, directed it to the pearpc directory and typed in " ppc macosx.pearpccfg" <- (my newly saved config file), i got some action - the ppc window opened up. but now it says that there are no images... refer to ss. now what do i do?

Errgh... ignore above posts. I got it all running smoothly. Apple OSX Panther on my PC :woot: .

If you need to convert dmg to iso :shifty: (BT) :ninja: , then google for "dmg2iso" and you'll find a nice and easy command line program which does it quickly.

BTW, I used Darwin to get mine running. How can I do it without Darwin?

Please help!

I'm unable to boot MAC OS X 10.3.4 with pearpc.....

I've tried with a NERO iso as well as with a ALCOHOL iso image....

MAC OS X 10.3.4 DVD is from my MAC G5... do you think my problems has to do with this OS version?

If I try to boot with pearpc 0.2.0 I see no boot partition from CD, instead with pearpc 0.3.1 i see the partition 3 from CD as bootable, but as soon as I boot, i receive a

[iO CUDA] Keyb reg1

and the installation hangs with apple logo on grey screen with no progress.

Trying to boot (pearpc 0.3.1) with prom_env_machargs = "-v" , I see that MACOS waits for boot device and then launch CRASHREPORTER.

Hier my configuration:

## PearPC Configuration File

##

## Resolution

##

## 0: 640x480x15

## 1: 640x480x32

## 2: 800x600x15

## 3: 800x600x32

## 4: 1024x768x15

## 5: 1024x768x32

##

## default: 2

#ppc_start_resolution = 2

##

## Redraw interval (in ms)

## must be between 1 and 999

##

## If you set this higher, PearPC will spend less time doing redraws (and so run faster)

## but feel less responsive. You should adjust this to your computer speed and personal

## preference.

##

## Setting this to a value less than 10 is silly.

##

redraw_interval_msec = 40

##

## Loader

##

##

## Boot method

## this can be

## 1. "auto", prom will boot the first bootable partition found (default)

## 2. "select", prom will show you a list of bootable partitions

## 3. "force", prom will load and boot the local file prom_loadfile

##

prom_bootmethod = "select"

## Example of how to use "force":

#prom_bootmethod = "force"

#prom_loadfile = "test/yaboot"

#prom_env_bootpath = "disk"

##

## bootargs: don't change unless you know what you are doing

## machargs: set to "-v" to get a verbose startup

##

#prom_env_bootargs = ""

prom_env_machargs = "-v"

##

## This is needed if you want to boot Mac OS X

##

prom_driver_graphic = "c:\ppc\video.x"

## This will adjust the position of the initial page table (don't change)

#page_table_pa = 104857600

##

## CPU Config

##

## Processor Version Register

## Defaults to 0x00088302

## Only change if you know want you are doing

##

#cpu_pvr = 0x00088302

##

## Main memory (default 128 MiB)

## must be >= 64 MiB

##

memory_size=0x10000000

##

## IO Devices

##

##

## PCI IDE Config

##

## Drive type will be set according to file extension:

## .img: Harddisk (filesize must be multiple of 516096)

## .iso: CD-Rom

## Or you can override this by specifying the type via

## pci_ide0_master_type / pci_ide0_slave_type

pci_ide0_master_installed = 1

pci_ide0_master_image = "c:\ppc\macosx_3gb.img"

pci_ide0_master_type = "hd"

pci_ide0_slave_installed = 1

pci_ide0_slave_image = "osx.iso"

pci_ide0_slave_type = "cdrom"

##

## Network

##

## Choose one of the cards

pci_3c90x_installed = 0

pci_3c90x_mac = "de:ad:ca:fe:12:34"

pci_rtl8139_installed = 0

pci_rtl8139_mac = "de:ad:ca:fe:12:35"

##

## USB

##

pci_usb_installed = 1

##

## NVRAM

##

nvram_file = "nvram"

Please, please, please (three times, ehm........)

Could someone help me?

Thanks in advance

Some people on this board have been curious about performance, so I will post my findings. I am running PearPC .4pre with Native CD/DVD-ROM support in Windows. My specs are a 2.0GHz Celeron Processor with 256MB DDR RAM, 55 GB Total HDD space, Intel Integrated Graphics, Windows XP Media Center Edition 2005.

My Times:

Time to boot to usable desktop: 4 min. 18 sec.

Time to Open "About this Mac..." on Apple Menu: 7 sec.

Time to open MacOS Hard Drive: 11 sec.

Time to open Calculator: 20 sec.

Time to switch calculator to advanced mode: 3 sec.

Time to open Text Edit: 14 sec.

Time to open Quicktime: 15 sec

Time to open Safari: 51 sec.

Time to open System Preferences: 34 sec.

Time to open Microsoft Word 2004: 4 min. 7 sec.

Time to shut down: 23 sec.

I didn't even bother to install Photoshop or iTunes, iDVD, GarageBand. or Premiere. About this Mac... claimed I had a 775 MHz PowerPC G3 processor with 128 MB RAM. Hope this helps some realize how slow PearPC is. However, I will say that it is improving. the first version, it took me 5 hours to install MacOS X Minimal. With this version it took me 2 1/2 hours, making it twice as fast. Right now I am getting about 8.8x slower than a real Mac G3. If the doubling of speed keeps up, around version 1.0 should be close to full speed for the lowest end of G3 processors, but realistically, it may never happen. It's still fun to dream.....

Hmm.. im also using .4pre with 10.3 Panther.. I am running it on dual RAID raptors with an AMD 64-bit 3800+, 1024 RAM, let pearpc have 800 megs to use.

My Times:

Time to boot to usable desktop: 2mins

Time to Open "About this Mac..." on Apple Menu: 2 sec.

Time to open MacOS Hard Drive: 5 sec.

Time to open Text Edit: 5 sec.

Time to open Safari: 10 sec.

Time to open System Preferences: 5 sec.

I don't know what it is but it runs very resposive on my system, almost as good as the real thing and is 90% usable! Also, in "about this Mac" it reports me having a 1.3 GHZ g3

Yeah, it's important to increase it's memory from default 128 to at least 256, maybe even 512 if you have some to spare. It can increase performance by around 5 - 20% depending on what you do.

Personally, I installed it yesterday, reporting my P4 2.6 GHz as a 1 GHz G3. :)

They're working quite rapidly with this software, keep in mind it was just one year ago since they got Mac OS X to start-up at all. I can't wait until they start fixing the performance -- hopefully there's some work to do here and they have mostly focused on features and stability so far.

They're also starting to work on sound support now. Yay :)

Show off! I guess this means OSX is really runnable in an x86 environment.. Now the next question, is it usable?

For me it's about as usable as being logged in to a terminal server, via VNC, or something like that. A little "laggy" but certainly fast enough to play around and "try a Mac". Actual Mac users has said OS X 10.3 takes around 30-60 minutes to install and that's what it took for me too, so it's not like it's ultra slow, taking hours to install, assuming you have a 2+ GHz computer at least.

HMmm....my laptop is coming in and it's goign to be a 3.2Ghz with 1024Mb of Ram. If this project gets just a little bit better, I would probably install OSX on my system so I can have Linux, Windows AND OSX.

Also, would it be possible to create a script or edit the boot.ini so that you can have an option to BOOT into PearPC + OSX?

    • Microsoft is making Windows 11's context menus faster, simpler, and configurable

      By Yogurth · Posted

      The biggest issue in this version of Win 11 context menu, from usability standpoint, is the movable row with basic commands. Think of a car analogy...if You turn the week left the infotainment screen will move right and vice versa. With how it works now Microsoft made something forbidden in designing in any UI, software or hardware. I can't grasp who were the morons within Microsoft suggesting it was a good idea and gave it a green light.
    • LibreOffice 26.2.4

      By Copernic · Posted

      LibreOffice 26.2.4 by Razvan Serea LibreOffice is the free power-packed Open Source personal productivity suite for Windows, Macintosh and Linux, that gives you six feature-rich applications for all your document production and data processing needs: Writer, Calc, Impress, Draw, Math and Base. Support and documentation is free from our large, dedicated community of users, contributors and developers. You, too, can also get involved! Choosing Between LibreOffice Still and LibreOffice Fresh: LibreOffice Still is a good choice if you value stability, a longer support cycle, and a more conservative approach to software updates. It's suitable for businesses and organizations where reliability and compatibility are crucial. LibreOffice Fresh is ideal if you're an enthusiast or an early adopter who wants to stay on the cutting edge of LibreOffice development and is willing to accept more frequent updates and occasional minor issues. Features: Writer is the word processor inside LibreOffice. Use it for everything, from dashing off a quick letter to producing an entire book with tables of contents, embedded illustrations, bibliographies and diagrams. The while-you-type auto-completion, auto-formatting and automatic spelling checking make difficult tasks easy (but are easy to disable if you prefer). Writer is powerful enough to tackle desktop publishing tasks such as creating multi-column newsletters and brochures. The only limit is your imagination. Calc tames your numbers and helps with difficult decisions when you're weighing the alternatives. Analyze your data with Calc and then use it to present your final output. Charts and analysis tools help bring transparency to your conclusions. A fully-integrated help system makes easier work of entering complex formulas. Add data from external databases such as SQL or Oracle, then sort and filter them to produce statistical analyses. Use the graphing functions to display large number of 2D and 3D graphics from 13 categories, including line, area, bar, pie, X-Y, and net - with the dozens of variations available, you're sure to find one that suits your project. Impress is the fastest and easiest way to create effective multimedia presentations. Stunning animation and sensational special effects help you convince your audience. Create presentations that look even more professional than the standard presentations you commonly see at work. Get your collegues' and bosses' attention by creating something a little bit different. Draw lets you build diagrams and sketches from scratch. A picture is worth a thousand words, so why not try something simple with box and line diagrams? Or else go further and easily build dynamic 3D illustrations and special effects. It's as simple or as powerful as you want it to be. Base is the database front-end of the LibreOffice suite. With Base, you can seamlessly integrate into your existing database structures. Based on imported and linked tables and queries from MySQL, PostgreSQL or Microsoft Access and many other data sources, you can build powerful databases containing forms, reports, views and queries. Full integration is possible with the in-built HSQL database. Math is a simple equation editor that lets you lay-out and display your mathematical, chemical, electrical or scientific equations quickly in standard written notation. Even the most-complex calculations can be understandable when displayed correctly. E=mc2. LibreOffice also comes configured with a PDF file creator, meaning you can distribute documents that you're sure can be opened and read by users of almost any computing device or operating system.

    • Ladybird Browser is no longer accepting outside contributions thanks to AI

      By David Uzondu · Posted

      Ladybird Browser is no longer accepting outside contributions thanks to AI by David Uzondu The Ladybird Browser Project has announced it will no longer accept public pull requests and will limit changes to those made by its maintainers as it works towards its first alpha release. According to Ladybird's creator Andreas Kling, this is "not a change we make lightly," but the rapid shift in AI capabilities forced their hand. Previously, a massive PR implied that the person behind it put a lot of care into the code and is ready to "answer for the consequences." Now with AI, anyone can generate a PR without even understanding the bug fix or feature they want merged. The blog post goes on to say that the team is closing all open public pull requests immediately, and that maintainers will not treat external forks as a review queue for upstream Ladybird. Instead, the team wants outside contributors to focus on reporting bugs and running tests. Kling started Ladybird back in 2019 as LibHTML, a simple HTML viewer for his hobby operating system, SerenityOS, but by September 2022, it had turned into a full-fledged browser project. What sets Ladybird apart from the likes of Google Chrome, Apple Safari, or Mozilla Firefox is its totally independent engine, which does not rely on pre-existing codebases. The project maintains a strict policy against default search engine deals or user data monetization, keeping development funded entirely by donations and sponsorships. Generative AI is forcing open source project maintainers to rethink how they handle public code contributions (and the whole open-source thing in general). One month ago, a leak about the National Health Service (NHS) suggested the organization was planning to take all of its public repositories private ahead of a May 11 deadline, thanks to Mythos (an AI model that Anthropic believes is too dangerous to be released to the public) and its ability to find and write exploits for zero-day vulnerabilities. Thankfully, the Government Digital Service (GDS) issued a counter-report titled "AI, open code and vulnerability risk in the public sector" that stopped the shutdown by pointing out that hiding code does not improve security.
