Unlike most major new Mac OS X updates, Apple chose to continue supporting all the same Macs as the previous release of the operating system. This means that if your Mac was compatible with Mountain Lion, you'll be able to upgrade to Mavericks.

However, some Macs are still limited to Lion version Some older Macs can't even be upgraded to Lion, meaning they'll be stuck with Snow Leopard version That's not a good thing, because it could mean that Apple may not patch security vulnerabilities for those Macs for much longer.
Apple might stop releasing security updates for Snow Leopard in the near future. The now three-generations-old operating system costs Apple money and developer resources whenever a new security vulnerability needs to be patched. Apple continues to release Java 6 updates for Snow Leopard and for Macs that have upgraded from Snow Leopard to a later version of OS X even though Oracle is no longer making Java 6 patches available to the general public—which could possibly mean that Apple is paying Oracle for the privilege of obtaining the latest Java patches for older Macs.
For many generations of Mac OS X, Apple only released patches for OS vulnerabilities in the current and one previous version of the operating system. Apple eventually seemed to change its mind about supporting the then two-generations-old Snow Leopard after Mountain Lion became available, but only after a long delay before patching vulnerabilities in Snow Leopard's version of Safari that had been accumulating for several months. Unfortunately, nobody knows for sure how much longer Snow Leopard or Lion will continue to get security updates from Apple.
While Microsoft publicly announces its support timetables for Windows, and Canonical does likewise for Ubuntu, Apple has never given any official word to the public regarding how long each version of Mac OS X or iOS will continue to receive security updates. The good news is that most new Macs sold within the past several years can be upgraded to a newer version of OS X. Following are lists of Macs that can run a supported version of OS X. If your Mac is older than the ones listed, read on for suggestions on what you can do to upgrade to a supported system.
If your Mac isn't new enough to run Mavericks, it won't run Mountain Lion, either. If you're not sure which Mac model you own, you may find EveryMac and apple-history to be useful sites. RAM is cheap, and you can either install it yourself by following guides available online, or simply have an Apple-authorized repair technician do it for you. If your Mac can't handle Mavericks but does support Lion, finding a legitimate copy of Lion could be a little tricky if you haven't already purchased it. However, it's unlikely that Apple has any left to sell at this point.
Since Apple doesn't provide any way to purchase Lion anymore, your best bet might be to ask a friend who purchased Lion when it was still available. If they have a license that they're not using, they might be willing to help you out. Again, only time will tell exactly how much longer Apple will continue to release security updates for the now three-generations-old Snow Leopard operating system. If you still use a Mac with a PowerPC processor, including G4 or G5 Macs, Apple hasn't released any security updates for your Mac's maximum operating system for over two years now.
Apple hasn't sold any PowerPC-based Macs since Unfortunately, Apple doesn't give users any kind of warning when their operating system or Mac is no longer supported. Worse, when users run Apple's Software Update program, it misleadingly tells them "Your software is up to date.

This means that Mac users often have no idea that they're using unpatched, insecure software that could expose them to drive-by malware installations and other security problems. Lest you think that nobody would bother releasing malware to attack such old systems, in recent years malware has been found in the wild that was designed to attack multiple platforms, and often this malware has contained PowerPC native code.
This didn't just happen once; it has happened again and again. Universal binary malware can run on old Macs, too.

It certainly seems logical, but only time will tell how successful this tactic will be. Anyone still using Snow Leopard or Lion should strongly consider upgrading to Mavericks if their Mac supports it, or if not, they should buy new hardware if they can afford it. Let's face it, that's what Apple wants you to do anyway. But what can you do if neither Mavericks nor Lion is supported on your Mac and you can't afford to buy a new computer?blacksmithsurgical.com/t3-assets/irony/field-marshal-earl-haig.php
Mavericks on a early Macbook | MacRumors Forums
If you have one of the early Intel Macs that can't even run Lion, you have several options. While Apple may not support your Mac anymore, ironically Microsoft does; Windows 8. Alternatively, if you can't afford to buy a copy of Windows or just can't stand the thought of it —or if you prefer to support free and open-source software—there are guides online detailing how to install Ubuntu Linux on a Mac.
The latest versions of Ubuntu are still being made available for PowerPC-based Macs , including those with a G3 processor. It will still do a fine job as my headless home OSX server!

It starts sort of ok, about 30fps. But will gradually sink to under 10fps. I tried many things to fix it. In the end I threw in a spare Radeon I had lying around, you don't get boot gfx so have autologin turned on but it made a huge difference! Minecraft stays around 50 fps. So it only affects those with old macs, boot. Cake Day. Looks like you're using new Reddit on an old browser.
