iMac HDD replacement - DONE!
during the last days I noticed my iMac getting so slow,
investigating this I found out that my Harddrive was about to die.
Today I replaced the old HDD with a new one in a high risk operation - taking two hours - to disassemble my iMac and reassemble it.
Well fresh install is just done. All TimeMachine Backups restored.
:)
Looks good!
