I have a MacBook and we recently installed some OS updates, and the system prompted us to restarted which we did and when it rebooted the system hung on the white screen with the spinning wheel for at least a couple of hours. So we had to hold the power button down to get the system to shut down, so we rebooted and it stalled at the same screen, so we did a hard shutdown, booted into safe mode which worked fine, and then rebooted from safe mode normally, and it booted fine into normal mode. Only thing the system is running very slow, and it seems unresponsive. As in the system would normally take about 40 seconds 1 minute to load the desktop now it takes about 5 minutes or so and every action that we do such as clicking on an icon takes about 5 minute for the action to complete. Time Machine has not been setup, so there are no backups. First Aid reports no problems with the disk, and really we could format/reinstall the OS if we needed to, but is there any solution?
