It’s a case of good news/bad news for Apple users. If your Mac is running OS X Mavericks right now, it will be able to handle OS X Yosemite. However, iPhone 4 users will need to update to a newer device if they want to access all the new features in iOS 8.
AppleInsider reports that the system requirements for Yosemite listed by Apple are identical to those for Mavericks, which means that the following systems will be able to run OS X 10.10:
- MacBook Pro: mid-2007 or newer
- MacBook Air: late 2008 or newer
- iMac: mid-2007 or newer
- Mac mini: early 2009 or newer
- Mac Pro: early 2008 or newer
- MacBook: late 2008 aluminum, early 2009 or newer
- Xserve: early 2009
Sadly for iPhone 4 users, the news is not so good, as Apple is retiring support for the device’s A4 processor with the debut of iOS 8. The oldest iPhone now supported will be the iPhone 4S, which uses Apple’s A5 CPU.
iPad users who own an iPad 2 or newer will be able to run iOS 8, Apple retired support for the original iPad and its A4 chip when it launched iOS 6 in 2012.
OS X Yosemite and iOS 8 are scheduled to be released to users this fall. Both upgrades will be free to users.
