OS X Yosemite Developer Preview 5 Release Notes

Known Issues

• Migrating from a user account encrypted with legacy FileVault may not restore files.

• You cannot restore from a Time Machine backup of OS X Yosemite using the system restore utility on earlier versions of OS X. Doing so will prevent your Mac from booting. To fix the issue, boot into your OS X Yosemite Recovery Partition and run Repair Disk on the un-bootable volume.

  Alternatively, you can run the following from a pre-OS X Yosemite partition:

  • /Volumes/<10.10 Partition>/usr/bin/afscexpand /Volumes/<10.10 Partition>/usr/sbin/kextcache

  • /Volumes/<10.10 Partition>/usr/sbin/kextcache -u /Volumes/<10.10 Partition>

Known Issues

• Shared purchase history pages on Mac App Store and iOS App Store are disabled.

• Items already owned by family members must be re-downloaded from the Purchased page (not Store pages) to get them free of additional charge.

Known Issues

• App icons may stay in the Dock after you have stopped using the corresponding app on another device.

• Handoff will not work on systems configured with multiple user accounts.

• Handoff icons may not appear in the Dock after using the corresponding app on another device. Trying another Handoff-supported app may resolve this issue.

Notes

• iCloud Documents & Data created with OS X Yosemite Developer Preview will be deleted from the servers during this beta period. Information downloaded and not deleted from your Mac will remain on your Mac and will re-sync after the data wipe occurs.

• Migrating to iCloud Drive will disable Documents & Data syncing for your iCloud account on OS X Mavericks and earlier Macs, as well as iOS 7 and earlier devices.

Known Issue

Some account password prompts may request the same login information several times before dismissing.

Note

Only Aperture 3.5.1 will run on OS X Yosemite Developer Preview 5. Older versions of Aperture will not launch.

Known Issues

• It may not be possible to enable My Photo Stream or iCloud Photo Sharing if both iPhoto and Aperture are present on the system.

• Text and other UI elements, such as checkboxes and radio buttons, may be clipped or not display properly.

• Importing and exporting images, adjustments, and book PDF generation may be slower.

• Thumbnails and images may occasionally be out of sync when in Split Browser mode.

• Printing a book to Preview from the local printing dialog may result in an error.

• Thumbnails of newly imported PDFs may temporarily show incorrect color.

• Adjustment and zoom sliders may not respond to single clicks and need to be dragged to operate.

Known Issues

• It may not be possible to enable My Photo Stream or iCloud Photo Sharing if both iPhoto and Aperture are present on the system.

• Text and other UI elements, such as checkboxes and radio buttons, may be clipped or not display properly.

• Application window may not be restored to its original size after exiting Full Screen view.

Known Issue

The Color Picker may not allow color selection.

Notes

• Subpixel rendering is now on by default for all web content. Websites or in-app web views with extremely tight design constraints may render differently.

• In OS X Yosemite Developer Preview 5, CSS object model getters Element.client{Left,Top,Width,Height} and Element.offset{Left,Top,Width,Height} will return rounded double values based on subpixel layout and rendering metrics instead of fractional values. Element.scroll{Left,Top,Width,Height} will return integral values.

Known Issues

• Date & Size limits set in Safari are not enforced in Developer Preview 5.

• Safari may stop responding while loading video when playing Netflix content.

• On certain machines, some forms of protected content, such as Netflix, may fail to play back. To resolve, hold down Option during the next reboot and select your OS X Yosemite partition.
