In line with yesterday’s report, Apple has today posted the first public beta version of Mac OS X Yosemite, build 14A299I. To get your hands on the pre-release version of Apple’s next generation desktop operating system you’ll need to be a registered member of Apple’s Beta Program.
After logging into your account with your Apple ID, you’ll have information about the latest beta version — which, by the way, coincides with the one released to developers on Monday— and click the button that will lead you through the steps you need to take to get this version of Yosemite.
Of course, the first step is always to make sure your Mac can run OS X 10.10 and, if checked, do a backup of your device, just in case.
Finally, to download and install Yosemite beta, just tick the accept box and you will get a redemption code and the Download button. The Mac App Store will open with your redemption code already entered, and then just click on the Redeem button.
However, since you are running software still in development you need to be aware of the issues you may face. Apple lists a couple of them:
• Safari may hang when playing certain Netflix content.
iPhoto and Aperture
•iPhoto 9.5.1 and Aperture 3.5.1 are required on OS X Yosemite. Update to these versions from the Mac App Store.
• When entering edit mode in iPhoto, a black screen may be displayed instead of the selected photo.
• Photo Stream and iCloud Photo Sharing may not function properly when both iPhoto and Aperture are installed.
• The shared purchase history page on the Mac App Store is disabled for Family Sharing accounts.
• iCloud Drive may appear empty in the Finder after first time setup. Restart to resolve this problem.
• AirDrop may not show nearby Macs.
• Sending files to another Mac using AirDrop may not work.
