Time wasted

Tilly’s (Isobel’s really) MacBook stopped working in March. I tried to fix it and was left with a formatted hard drive and unable to reinstall the os.
I said we’d have to wait until Apple stores reopened.
Then the other day, when Apple stores are starting to reopen, I thought why not look for a local independent repairer. So I did. And now it’s fixed.
I also think I’d know how to fix it now...
