I posted on Twitter yesterday about some problems I was having with my aging MacBook. For the last week or so, it seems, my laptop is locking up–freezing–several times a day. So bad is the lockup that all I get is the spinning wheel cursor and nothing works. No keyboard commands, nothing. I have to physically power down the machine and reboot.
Well! I might be a software developer in my day job, but I started out as a troubleshooter, and a pretty good one. Friends and family are often asking me for help. So why not turn those troubleshooting skills to my own problem?
At first, I thought it might be related to my external harddisk. I have a 1 TB external disk connected to the MacBook via Firewire. All our media is stored on this disk (which is in turn backed up to the cloud via IDrive). When the computer would freeze, I noted that the light on the disk (which is a kind of roving white light akin to the roving red light that characterized Michael Knight’s car, Kitt in Knight Rider) was frozen as well, as if access to the disk was causing the problem. I ran some checks on the disk but nothing turned up. The disk, at least according to the disk software, is in good shape.
Well, maybe it was the connection to the disk. Maybe the cable was bad. One way to tell for certain would be to shut off the disk and disconnect the cable and see what happens. I did that. It seemed to work at first, but before long, the computer would lock up again. The lock-ups seemed arbitrary. No one thing was causing them.
