Mac OS X 'Leopard'-related Discussion


Recommended Posts

My mates Leopard disc that arrived yesterday is 10.5.1, I guess as they roll out each revision they burn that onto the new discs and slowly but surly the 5.0 supply runs dry, a good tactic for keeping people up to date.

I know far too many people (mainly PC users) who're still running Windows XP SP0 and didnt even realise you had to update PCs, no doubt i'll be converting them to Mac users, just give me time

And I've run into even more Mac users who're still running OS X 10.3.9 or w/e and have no idea what "Tiger" or "Leopard" is.

Thanks everyone for your post. I was considering buying Leopard and wondered if the disk in the retail box would be 10.5.1 or I would have to update it myself. Thanks again.

truthfully does it even matter? a brand new leopard install only installs 4 updates... itunes, quicktime, ?????, and 10.5.1... it takes tops 10 minuits from start to finish..

Remember leopard takes some time to index everything. That'd explain the "Stuck in the Mudd" feeling.

No, it was just sluggish all the way around - Vista indexes everything too, but it's a different kind of slowness, mainly the HD getting hit, but I always clean install Windows, and after about a week, Vista was happily plugging along. Tiger to Leopard (on a week old system no less) was just bad. Felt like the mouse cursor was lagging, mousing over the dock was slow, slow to open programs, some programs weren't loading correctly...

I haven't experienced any problems with the new install - like Windows, a clean install is definitely the way to go.

The only time an upgrade seems to work smoothly is a clean install of the old OS then IMMEDIATELY upgrade on top of that but.. hardly worth the aggro to be honest :D

Plus, upgrade installs aggravate drive fragmentation thus are GUARANTEED to slow down system performance

Mac OS has defragments all files smaller than 20 MB whenever they're opened.

On my system there are 28 files that are larger than that assuming you ignore the iLife media (which should have been laid down in a single contiguous write when they were installed and wouldn't be touched by the installer anyway).

I think you'll find that's not true, download the demo version of iDefrag and just run the analysis scan, you'll see that 99% of the files on your hard drive are way more then 20MB, for example, system and swapfile.

I defraged a two month old Leopard install last night and got the boot time from 30 seconds to 12 seconds :p

Download the demo version of iDefrag and just run the analysis scan

I did: see the attached screenshot: it lists my system at 0.1% fragmentation (assuming I'm reading its statistics tab correctly).

This is a current-gen iMac (3 GB ram) upgraded from 10.4 to 10.5 two days ago. It has the standard assortment of applications you'd expect to find in a new-media/marketing firm. Photoshop, Illustrator, Compilers, Finalcut, office, etc.

Maybe it's returning bogus information? The product page indicated it wasn't leopard compatible.

you'll see that 99% of the files on your hard drive are way more then 20MB, for example, system

I think you'll find the opposite is true:

Count the number of files in /system large than 20 MB
(me@work : /system)$ sudo find . -name "*" -size +20000k | wc -l
	  17

Count the number of files in /system not larger than 20 MB
(me@work : /Library)$ sudo find . -name "*" -size -20000k | wc -l
  321053

You're off by 5 orders of magnitude.

Other directories like /Library, /bin, /Applications are in a similar state.

and swapfile.

The files in /private/var/vm are created and destroyed as needed: trying to defragment them is pointless. (see: Mac OS X - A Systems Approach) as they won't necessarily exist past the current session never mind across reboots.

For the record, dont run iDefrag on Leopard, as they state on their site this can cause some very nasty problems, instead boot of the iDefrag DVD you burn after buying the product.

My Mac loves defragging. Try a full defrag sometime booting from the dvd

    • "The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months¨ I'd prefer to see the lowest price in over a year
    • Glad these prices are starting to come down, but that is still crazy. I bought the 2TB 9100 Pro (slightly more expensive version with PCIe 5.0) last year for $240.
    • The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months by Sayan Sen Yesterday, we covered a really good deal wherein you can get a 4TB TeamGroup T-FORCE G50 NVMe PCIe Gen4 SSD for a low price of just $400 with a special discount coupon. That's just $100 per TB, making it a very good offer during these hard times. The deal is still live, so you can check it out in its dedicated article here if you do not want to miss out. Meanwhile, if you don't have that kind of budget but still wish to buy an SSD for a good price, the 2TB variant of the TeamGroup SSD at $280 its lowest price in over three months. Meanwhile, those seeking 2TB but faster performance can check out Samsung's 990 PRO, which has hit the lowest price also in the last quarter or so, as it's on sale for $370 (purchase links under the specs table down below). Thus, you want a faster drive, get the 990 Pro, or you want more capacity, grab the TeamGroup 4TB linked in the first para. The 990 PRO is a PCIe Gen4 NVMe SSD and still one of the fastest drives available today for under $500. Speaking of fast, sequential reads and writes are rated at 7450 MB/s and 6900 MB/s, respectively. The random throughputs for reads and writes are 1400K IOPS and 1550K IOPS, respectively. The 990 PRO is based on Samsung's 7th Gen V-NAND flash, and it too is TLC. It packs 2 gigs of LPDDR4 DRAM cache, which helps the random performance. The endurance rating for this is 1200 TBW (terabytes written), which should be sufficient for most users. The Samsung 990 PRO is compatible with the PlayStation 5, but if you are going to use the 990 PRO on a PC, check out the Samsung Magician app that lets you track your drive's health, update its firmware, customize various settings, and more. The tech specs are given below: Specification TeamGroup T-FORCE G50 2TB Samsung 990 PRO 2TB Interface PCIe 4.0 x4, NVMe 1.4 PCIe Gen 4.0 x4, NVMe 2.0 Form Factor M.2 2280 M.2 2280 Controller InnoGrit Controller Samsung In-house Controller NAND Flash 3D TLC 3D TLC DRAM Cache None (HMB supported) 2GB LPDDR4 Sequential Read (Max) 5,000 MB/s 7,450 MB/s Sequential Write (Max) 4,500 MB/s 6,900 MB/s Random Read (4K) Up to 600,000 IOPS Up to 1,400,000 IOPS Random Write (4K) Up to 700,000 IOPS Up to 1,550,000 IOPS TBW (Endurance) 1,300 TBW 1,200 TBW MTBF 3,000,000 hours 1,500,000 hours Operating Temperature 0°C to 70°C 0°C to 70°C Storage Temperature -40°C to 85°C -40°C to 85°C Shock Resistance 1,500G / 0.5ms 1,500G / 0.5ms Heatsink Patented Graphene Heat Spreader No Get them at the links below: Samsung 990 PRO SSD 2TB (MZ-V9P2T0B/AM): $369.99 (Sold and Shipped by Amazon US) TEAMGROUP T-Force G50 2TB SSD (TM8FFE002T0C129): $279.99 (Sold by TeamGroup, Shipped by Amazon US) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.

    • If you can't spell a simple word that 2nd graders learn, your entire argument is suspect.
    • And here goes the "Won't someone think of the children" brigade. Get stuffed mate. This has NOTHING to do with making the internet safe. It's about tracking adults, spying on your online activity, and sending the boys around when they don't like something you post. Also, again, parliament have voted TWICE against this, and Starmer is going ahead anyway. THAT is anti-democratic bullsh**. They will use this law to track you, they will use this law to control you, and they will use this law to punish you if they don't like what you do, even if it's legal. And your data? Say bye bye to that. It'll be on the darkweb in weeks. I'm not some rando online. I've been an IT professional for 40 years, many of it in security. I know exactly what this means and what will happen to your data. I do not consent and I will not comply.
