[QUOTE="IWT, post: 1877455, member: 83420"] Hi Peter You make a good point and ask a very relevant question. In the rebooting process, Bluetooth is only activated/acknowledged late in the process, consequently holding down Cmd and R is not recognised in time to initiate Recovery Mode - unless you are very lucky. In my experience, such as it is, I could never enter Recovery or Safe Mode. Hence the need for a wired KB, which is recognised almost from the start of rebooting. Time Machine and Carbon Copy Cloner (CCC) backups are not affected. Any KB, even a Windows one will do and if you look around, you can get wired KBs inexpensively. The more recent KBs from Apple have rechargeable batteries and they are charged by connecting the KB via USB cable directly to the iMac. This also makes it wired. HTH Ian [/QUOTE]
