Hi all - for some time now my iMac hard drive has been working hard (I can hear it) even when doing light tasks such as browsing, listening to music and working on Word docs. About once a day I hear an ominous clunky/click. I am interpreting this as the hard drive being on its way out but have not had time to deal with it but made sure Time Machine and other backups are doing their thing. However, it's now reaching the stage of lots of spinny beach balls and really random errors that need restarts - can't open iCloud options, can't open General preferences, and getting really slllloooow. I can't ignore it any longer, so need to work out what my options are. My previous machine was a white Macbook - it had identical issues and when the drive died I replaced it myself. I'm not confident about doing this in my iMac, I would rather get a professional to do it. I live an hour away from my nearest Apple shop - what's my best option? By best I mean quick and professional, not looking for a budget option IYSWIM. Send away to Apple? Lug it to the nearest Apple shop? Seek out an independent repairer? Thanks in advance for your advice.
