I have downgraded fron Yosemite to Mavericks using the OSX Internet Recovery.
It went fine, but now the "last modified" dates on my applications in finder are all wrong, some even show 2013 and i bought this macbook pro last summer, so it's impossible.
I have checked the date and the time zone and even done another clean install: nothing changed.
Any way to fix?
Are sure this is wrong? Because they may just be time stamps for when that app was created.
give an example and someone else running Mavericks can confirm for you.
Generally speaking I wouldn't suggest users keep flipping back and forth between OS installs.
If you're unsure about an upgrade, wait until adoption has stabilised and they iron out the big bugs, in the mean time do a bit of research into whether the features and design are to your liking and needs.
Any changes after upgrading, unless super critical, may just take some getting used to.
But maybe that's just me. I tend to be faulty adaptable and can stomach minor changes.
Of course if something turns out to be critically broken such as a very important feature for your workflow or an incompatibility with another piece of software or hardware, by all means roll back.
Always make backups before major updates.
