OS X Mountain Lion to be released today - available now

Apple’s next major desktop operating system update called ‘Mountain Lion (OS X 10.8)' will be made available via the Mac App Store today for $20.

Mountain Lion focuses on incorporating features from iOS to the Mac; some of these include the Notification Center, expanded iCloud support, Reminders, and much more, but if you want to read about exactly what has been incorporated into Mountain Lion, Apple had previously posted a 200+ feature list – so it’s worth a read if you’re planning on updating today.

To be able to install the update you will need to be running either Mac OS X Lion or the most recent version of Snow Leopard (10.6.8). 

Update: OS X Mountain Lion is now in the App store, go get it! You can also check if you're eligible for a free upgrade here.

You can also join in or read the Mountain Lion discussion in our forums, or any other Mac related topics here.

With the Game Center what all games can be played on Mountain Lion? Can you play all the iOS game apps or what?

No. But certain games will be able to play against the iOS version too. So if you're playing a game on ML, and your friend is on iOS, you can play with / against them on certain games. But for that info you'll have to do some research because I'm not a gamer and haven't looked at the list of games supporting it. I wont even load Game Center. Ever. lol.

Not sure if I should install it on my MacBook Air with 2GB

Ho3 much faster is ML over Lion and is it better at memory management than Lion?

If you're running Lion, sure, go to ML. It's going to be better than Lion.

I know it's better but will it slow down my MBA?

So, any chance of getting this apart from the App Store (legally)?
I'd prefer it on some form of physical media without having to go through App Store, like they did with the USB stick in 10.7

Download on the App store, then put it on a USB stick like most people. It allows for clean installs and is VERY easy to do. It's virtually set up for you to do it. And if not, there's always Lion Disk Maker, a free app that will find the ML installer, and make a USB stick installer for you. That's free. So yeah ... go buy it, then run that with a USB stick and make one and put it away. I did a fresh install and it's running beautifully and on my SSD it only took a few mins to install

Have to love their 200+ features, always a lot of laughs... (It is almost a bit sad, because they are totally serious.)

Stuff like: Keyboard shortcut for Save As
Is freaking hysterical, not only it being a 'lacking' feature, but that it makes the OS level list of new features to round out the 200.

Most of the things on the list are not important enough that they would even make the Windows version change lists for a small update, let alone a full version update. If Microsoft counted out the features at this level of detail, just Vista to Windows 7 would be about 10,000 items.

Another true statement. ML is nothing more than a service pack with a few performance tweaks under the hood. 95% of the things listed as "200+ new features" are common items in the computing world. Well, common to every other OS except OS X until now. Charging $20 for it is criminal!

Windows 7 is to Vista what ML is to Lion. Yet MS charged a lot more than £13.99. ML is not a service pack. It's got a bunch of genuine new features. Service packs don't add entire feature sets... they're bug fixes and security updates that were pushed out over the last couple of years rolled into one download.

Very big difference. Morons like you will never understand this because you don't want to.

I started downloading off the App Store this morning before I went to work. I'm tempted to login remotely and try to install but maybe I should just wait until I get home.... hmm...

What about improvements in graphics ? OS X is **** when it comes to games (on the same hardware, same game, I get 30 - 50 fps on OSX but 70 - 100 Windows 8).

For how snappy the desktop UI feels it is really really disappointing to see such a difference between the frame rate of a game in Windows vs OS X . They don't seem to be that concerned when it comes to sorting that out.

Unless Apple rebuilds the kernel, driver, and other layers from the ground up, it will NEVER be as fast as Windows NT.

There are a lot of serious technical issues with the way OS X is designed, and stuff that a lot of outside engineers like myself warned Apple about and even petitioned them to reconsider. Instead they went with the quick and easy route, and even damaged performance to make things work in various early OS X releases.

OS X needs to become OS XI and built from the ground up using something that is NOT MACH and NOT BSD and NOT Apples horrible mangling of the kernel API into their frameworks.

This ^^.

And calling OS X "the world's most advanced operating system" was a lie from the beginning. It is purely a marketing ploy and very far from being a truthful statement. Like thenetavanger says here, I HOPE they rebuild OS XI from the ground up and at least get a little closer to their false claim.

Wow ... not one bit of info to back up your claims.

Go on. List me .... 20 serious issues with OSX that engineers warned Apple about. And detail what and why.

thenetavenger is a one post wonder - makes a post then runs away because god forbid him actually engage in a conversation where he is exposed as little more than a 'copy and paster'. I've already shown him up to be incorrect and not a single thing I said he has refuted so there is no use expecting him to come back and address the challenge you've laid out. IMHO there should be a rule on this forum - if you make a claim then you either must back it up within 24 hours or be permanently banned from the forum.

It's sad that I knew this was probably going to happen, but Lion seems to be gone from the App Store. So if you're one of the many who can't run Mountain Lion and you haven't bought Lion yet, now you can only get Lion by buying the USB stick. And presumably while stocks last.

This will bad for those who not bought Lion yet, then realise that ML is not working on their mac, so those will can't buy any OSX...

If you can't buy Lion, and you're still on Snow Leopard, you're better off.

You had a year time to make up your mind, purchase and download it. And the only option being the USB stick is just nonsense. Everyone who purchased OS X Lion can log into the App Store and download the file with up to five Macs. You figure the rest out.

I made up my mind and I avoided it (and will continue to do so) because all reports suggest it'll run like crap on my MacBook.

But Lion is a requirement for iCloud and there are plenty of Macs in use that can't run Mountain Lion (or higher). Anyone who hasn't purchased it yet can no longer do so from the App Store. It's gone. So if they want it from today they have to buy the USB stick. No nonsense there.

Apple threw their users a rope this time around because Lion is available on USB. Mountain Lion isn't. So when the next round of Macs are cut-off with 10.9 they had better be running 10.8 before it hits the store.

There are plenty alternative methods of obtaining it. Simple as that.

Well I only know the App Store and Apple Store. So please list the others.

And as it turns out, the Lion USB is no longer available on the US Apple Store so the rope was a short-lived one.

It's not as stupid as you think. Having everything on there own store means better security you know what you get will be safe. Yes it means developers might make less than they would if they could sell app another place due to the apple cut of the profit they make by listing it on there store.

BUT and this is a massive BUT
The developers get free web hosting, free advertising, and the product is known and labelled safe and trusted. In a way i think this would actually make the developers better off!

It has its conns but also pros i guess the biggest con for me would be if i was to develop something apple didn't want on there app store! This would be the only real disadvantage i could think of.

No point on commenting on apple making money. We all know what they do and how they do it and yes its disgusting.

I think a lot of people downloading it now, and the server can't handle it.

It wasn't working for a lot of people in the UK. Now it should be though.

Must... not... update... stupid MacBook Pro.

Oh, I don't know if I will be able to resist the temptation of a software update.

My macbook is too old.

My 4 year old mini is also not supported contrary to what somebody here said, and more or less called me a lying hater. Oh well, I now have a nice computer to run Win8.

If you sync with anything that requires sync services do not get this OS, there is no sync services in Mountain Lion. So if you use a BlackBerry for example no more syncing.

You mean to Lion. (?)

Well, no, and yes.

Mountain Lion improves and optimizes Lion in much of the same way that Snow Leopard did to Leopard.

I meant the same way. Lion = Leopard, Mountain Lion = Snow Leopard

virtorio said,
I think he's implying that Mountain Lion is a refinement of Lion, in much the same way as Snow Leopard was a refinement of Leopard.

I'm saying the same

I upgraded and I was running Lion for a while, however after loosing some network capabilities with some hardware devices and with some versions of software needing to be upgraded (for a fee) to a newer version to be compatible - I dropped Lion and went back to Snow Leopard.

Lion also seemed to be kind of choppy on my Intel core 2 duo iMac with 2GB of ram.

Honestly, I am disappointed with Apple on Lion and probably will not try Mountain Lion. One of the main reasons why I decided to upgrade in the first place was because FaceTime was included.

I agree with Lion being a poor release, but everything I've read about ML is that it's the Lion Lion should have been.

You might want to change your information sources.

By default, it will only allow to install software from the mac app store. You can change this setting in "System preferences > Security and Privacy" to allow everything to install.

It is a personal choice. In settings, you can change it to MacApp store only, macapp store + identified devs, or anywhere.

That's just stupid... I'm sorry but it is, because this is going to be the start of appl moving towards the whole everything goes through the app store no installing from other sources, oh and by the way, want to make money writing apps, pay the 30% toll you never had to pay before... and once Apple does it, you know MS will follow later...

I thought you couldn't install Metro apps from any other source apart from the MS App Store (excluding enterprise situations).

Apple is stupid for doing this but they know they will get away with it because most of its users are home ones. Microsoft won't follow because they have the upper hand and don't need to try and screw as much cash out of its users as possible.

ingramator said,

Apple may be stupid enough to do this only because most of its users are home ones. Microsoft will never abandon the enterprise world or do anything so rediculous.

Yes. Because creating a whole new environment is much better for enterprise (requiring a total re-write of their software, if they wish to make use of it) than just adding some optional improvements to your current well established environment.

If it's on by default, then how is it a personal choice? Apple has already made the decision for you. If it was a personal choice then it should be off by default. Thus giving you the personal choice to turn it on or leave it off.

It's on by default because it's the most secure option.

It being a default does not take away the fact that you can turn it off hence its an option, or personal preference. If someone that doesn't know this gets the upgrade, then tries to install an app from somewhere other they'll get some kind of error message, they'll Google it, they'll turn off the option if they decide to, and they'll install the software. for people that don't know and don't need, they'll be more secure by default.

Actually, the default is "Mac App Store + identified developers", which means it's open to side-loading as long as the application is signed.

Not this version. But that lock may be in place in next or next to next version.

Well it isn't at that point yet and no one knows for sure if and when it will ever be that way so no point in tossing FUD around now about it. If it ever does become that way I guess we will be "Jailbreaking"/"Rooting" our Mac OS X and Windows installs.

The type of user here probably would care a lot. But I think that most other users will have less malware issues (especially in Windows) if it did come to that. I like the idea of setting the secure settings high by default. If the end user can't figure out how to change that, then they probably are better off not changing it.

Honestly, I'd be more worried about Microsoft locking down Windows in the near future. They've taken far more aggressive steps towards that goal.
