Older keyboards don’t work in Yosemite
After updating to 10.10.1 on my late 2012 iMac and my 2014 MacBook Pro, I find that my USB keyboard does not operate correctly on either machine. It was fine on Mavericks. I still like to use a ‘proper’ keyboard with real keys for typing rather than the current rubber button styles, so I use a Mac frameless USB keyboard. Is there any way to make the keyboard map correctly or is there an equivalent keyboard available that will work correctly with 10.10.1? Martin Booth I’m the exact opposite. I like the low-profile keyboards so much that as well as having them on all my Macs, I have an almost identical one with Windows keys for my PC. The issue with the old-style keyboards on MacBooks had been reported in Mavericks too, but it seems to have got worse in Yosemite. They either don’t respond at all, or suffer from keys that act like they’re stuck down. You can sometimes wake them by plugging a memory stick into one of the keyboard’s USB ports. It seems that the stick is able to register its presence with the MacBook and the keyboard can slipstream behind.
If that fails, there are still a few manufacturers making keyboards with larger keys and more positive tactile response. Try the Cherry G82-2702 Initial, which is about £18 on Amazon.
