Hi I purchased my MacBook Pro 13 about 8 months ago. Everything as been brilliant and I am really impressed with the performance my problem is last week I tried to restore my Mac back to factory reset. I fooled the instructions on the apple web site. Backed up my Mac using time machine I then shut down the Mac started it up pressing command R. Used the disc utility then followed the instructions i.e.: erase disk format in Mac OS extended (journeyed) reinstall Mac OS This where my problems start several times I tried this over there / four day with same outcome it never got to the end before error message saying couldn’t install. Tried disks utility to do first aid, erase mount each time operation failed. I was advised by a friend to install operating system on boot disk this I did and it worked ok but I can access my Macintosh hard drive I am sorry it a bit long winded but would appreciate som e help thank you

What version of macOS was it on before you tried the erase and reinstall? I would say try using internet recovery. Hold Cmd+Option+R on boot, and connect to wifi when prompted. It will load the recovery environment from the internet so it will be slower. This time, go into disk utility and select the entire physical drive, not just Macintosh HD, and choose APFS as the format and GUID or GTP whatever it says, I forget, as the partition scheme. Also name the drive whatever you want. Then close disk utility and try the reinstall now.

So I'm assuming you have a touch bar machine and one side both thunderbolt ports aren't functioning you mean? Are all ports recognized in System Information? I would say shut off the machine, then do a SMC reset. Shift+Ctl+Opt+Power Button. Power back up and try ports again.

Is this power related, or do usb devices work? Can you go to system information, then thunderbolt and take a screenshot and post it here.
