Hello all.

So Mail.app has been crashing on me of late, in the background (it would simply quit).

So today, woke up my MBP - and was met with Index is Corrupted etc. messages, and needed to reimport messages.

Tried - and it would hang on the Import stage.

Booted into safe mode. Tried it again, and all worked as should - imported 80k messages, and everything looked fine.

Restarted - met with the grey no-entry sign.

Booted into Restore mode.
Fired-up Disk Utility. Ran repairs. All indicated as fine, on both the HDD and SSD (with OS).

Restarted - same story.

What now?

Are you running 10.10 and if so have you enabled Trim on the SSD?

Joy. Did I need to disable Trim Support before logging into Safe Mode?

Have a look here then - https://www.cindori.org/trim-enabler-and-yosemite/ - head down to the "Recovering from stop sign on boot screen" section.

Best of luck. :eek:

Live and learn. Thanks. Didn't occur to me that this could be the issue, but most likely is.

Couldn't get the Terminal commands to work. So I'm reinstalling my OS off my flash. Should hopefully not take too long. Made a TM backup over the weekend, so if worst comes to pass - there's that. But will hopefully be back up and running.

And then I will disable Trim Support for good. Mostly because I keep forgetting to disable it, when I'm doing something that needs it disabled!!

It could also be a failing SSD but let's hope for the best.

Hmmm.

I held in option - selected the flash. It did the install bar. Now I'm back at the Restore screen - do I simply restart?

After reinstalling it should have booted straight into OsX. Make sure your drive with OsX installed on it is selected as the boot drive.

EDIT - does that USB have OSX installer on it or just the recovery mode? If the Installer isnt on the USB you're being sent to recovery mode to reinstall via the internet.

Aw shucks. It was.

Not looking good now - and I'd obviously prefer not to go via the Internet route.... Try a restart?

Do you have a second mac available so you can create a USB Installer?

6gb to download. Joy. I plugged the USB into the Mac Mini - and it looks fine, with the OSX "Install Yosemite" etc., - would there be much harm in trying things again over on the Macbook? Or would I be playing with fire?

How big is the installer file on the USB Stick?

A USB drive with the installer on it isn't going to work but so long as you created the installer properly, either manually or by using something like DiskMaker X, you could try just booting straight to that stick by holding the option key down at boot and selecting it.

It's about 6gb. Pretty sure I did it right - followed the same procedure as with ML, and that worked for me before.

It flashes up the Select Languages screen, but then something goes wrong - and it goes back to the Recovery Screen, which isn't working either, since it doesn't allow me to select some of the options.

I do hold down Option - and select the USB. The other option is my main SSD Drive - it doesn't see the HDD.

Getting a tad nervous now. Ran CCC sometime in last week, TM over the weekend, but a fair bit of work has been done since then, so I'm really hoping I don't need to restore.

Downloading Yosemite on the MM now, but it still has 4GBs to go...

Yoh!
