Just like it did with iOS 7, Apple is now allowing Mac developers to offer “last compatible” versions of an app in the Mac App Store, says a report in Macrumors. This makes it possible for developers to keep upgrading their software to the latest version of OS X, while still allowing those with older machines to download the last version of the software that was compatible with their hardware.
Apple sent out the following notice to Mac developers notifying them of this change:
Users who have already purchased your Mac app are now able to download previous versions, allowing them to use your app with Macs that may no longer be supported by OS X Mavericks.
If you do not want previous versions of your app to be available for download as a previous purchase, for example due to a usability or legal issue, you can manage their availability in the Rights and Pricing section of the Manage Your Apps module on iTunes Connect. To exclude a specific version, click “Manage iCloud download settings for this app.” For more information on managing previous versions, see the iTunes Connect Developer Guide or contact us.
This is good news for both Mac owners and developers. Mac owners who own older machines can be perfectly content staying with their vintage hardware, while developers can offer older versions of app to keep their legacy customers happy.
