I'm not able to start my iMac. Tried safe mode, disk utilities, reinstall none of them is working and every test just gives errors.
Mac os is 10.13.6. This iMac has a 2tb fusion drive. I'm not worried about data because back up is done using thunderbolt. I don't know other solutions.
Any solution?
iMac 27″ 5K, macOS 10.13
Well, if you tried everything it's impossible to tell you what to try, but long shot...
1.. Shut the machine down.
2.. UNPLUG the power lead to the computer and any peripheral devices.
3.. leave it for 10 minutes.
4.. Hold power Button in for 10 seconds
5.. Connect everything back up and restart.
Hi,
Thank you so much for your reply.
First thing tried was what you suggest. Than I took help from IT guy and run some tests. What he said is that it is hard drive issue. Because it is not installing fresh os, first aid shows errors. iMac doesn't start at all. Only thunderbolt worked. If i try to start, it just shuts down. I thought if some solutions missed than I can try. For repairing screen has to be removed. That is fearful for me.
I don't have any experience regarding installation on external drive.
If i install os in external drive, will mac start?
I'm trying to get repaired but if i can do this my self, I'll do.
Any pendrive can work or I've to use any specific.
A pen drive big enough may work, but terribly slow & prone to failure.
Once installed to an external drive if it doesn't restart from the external just hold Option key on startup to see boot choices.
Suggested drive...
OWC Mercury Elite Pro: USB 3.2 + FireWire 800 External Drive (macsales.com)
Thank you so much for your help.
This installation should be in empty drive or a drive with empty partition.
Installation in drive which has no partition can erase all data, right?
I'll try this. Thank you
Get an external drive to Install to.
Yes, an empty drive is best format MacOS Extended Journaled for 10.13 or earlier.
Thank you
I'm very happy that I could help my friend, do check back if you need more help along the way. :)
Thank you. I'll update once I try it.
Hi,
I can buy any drive with USB 3.2.
There won't be OS related issue using latest drive with old OS.
What do you think?
Most any, but give us a link to one you're thinking of so we can be sure.
