So, about this time last year, I noticed a very odd problem began to occur in my iMac (and seemingly after verifying my hard drive in Disk Utility to prepare for Lion); at startup, my Magic Trackpad and Apple Wireless Keyboard would not instantly turn on (as indicated by the green power lights). The times varied (with sometimes being instant, or close to it), but often could take anywhere from 5-30 seconds. So, I delved into various troubleshooting attempts:
- deleted Bluetooth and peripheral plist files
- changing the batteries
- re-paired the devices
- changed the batteries
- reset SMC and PRAM
- restored to earlier Time Machine backup
- standard reinstall of Snow Leopard
After doing all that to no avail, I turned to the Genius Bar. They used different trackpads and keyboards and booted from an external hard drive to come to the conclusion that it was a hardware problem, that the Bluetooth chip was defective. So, they replaced it. It seemed to work for a day or two, then the issue came back again. I ignored it and installed Lion not long after, and the problem, while not eliminated, was improved after that (though, I did notice that it would be a little worse after every 10.7.x update, but would get better in time). Flash forward to now, Mountain Lion, and after doing an upgrade install, the problem was still there. Due to other problems with ML, I decided to do a clean install of it, hoping it would solve all of my problems, this included. But lo and behold, the issue is still here, and I'm pretty tired of dealing with this thing for a year now (even if it's relatively minor). Anyone else had this problem (it seems to be a very rare issue based on Google)? Is it possible that it's not the Bluetooth chip or some OS X error, that it's some other hardware problem?
