I did see suggestions on the internet that if the graphics card has been changed this might be why the boot screen would not appear? The mac seems to have 2 500gb disks but when I looked in system info on the previous boots it appeared as 1gb drive. I do hear the boot chime again when I do this which is encouraging. Turning all the power off and leaving for 5 minutesĭoing a NVRAM reset using win key+alt+p+r. I think that this was a patch to Yosemite, not an update to El Capitan (?) 20 minutes later it rebooted and I heard the startup chime but no boot display at all. The problems started when I did a check for updates (Yosemite) and it installed an update.
Given that I never turned on a mac before I didn't know what to expect so just logged in using the administrator account and had a bit of a play. On getting it home I got it to boot a couple of times, *but* I don't ever recall seeing a boot screen or "apple logo" for any kind - it went straight to the login screen. I've just bought a second hand mac pro in order to compile ios apps.
