Clean installation on a 13 rMBP 2015 using a USB flash drive went just fine, although a core storage volume was created. Since I didn't enable File Vault, I went ahead and reverted the logical volume using the coreStorage command.However, I wasn't able to replace the codesign file in /usrs/bin with the OS X 10.9.4 version since I couldn't change ownership or file permissions. The system files are protected, apparently, which is probably not such a bad idea.Numerous installations failed, so I was forced to restore my original Yosemite time machine backup. The following programs refused to install (after which I gave up and restored my earlier system):- Tuxera NTFS for Mac- Little Snitch- iStat Menus- OS X Fuse- gdisk- Gutenprint printer drivers (I have an old Canon BJC printer)I'll wait and try again when some of the developers have had time to provide compatible programs.
