As a rule, I always clone my OS X to a different drive and try the install over there first, so that I did, I cloned my OS X 10.10.4 to an internal 300MB HD that I use as an alternate Boot or Sandbox to experiment, I followed all recomendations (repair permision, download 10.10.5 combo, execute combo, re-boot, Multibeast 7.5, re-boot, Success!!! all working fine..
So I decided to run the update for real on my system disk (this time to a SSD 240 GB), so I repair permisions, execute combo, and just when it re-boot (to complete the installation) my system died (black screen)
, and it was not because a power failure.
I was able to reboot again to 10.10.4 on my SSD, so tried again the update, and again black screen as soon as it tries to reboot to complete installation. Unfortunately it doesn't boot anymore to 10.10.4. on the SSD
I booted from my 300 GB HD, ran Multibeast 7.5 to the SSD (just in case) but it still doesn't boot, it dies on the screen with the little apple haldfway booting.
The 1st installation (trial) worked flawlessly on an exact copy of my system disc (except is was on a 300GB Hard Drive), but when trying to install on the SSD it did't even complete the installation. I'm sure is not drivers related ( I have a Radeon HD6850) as all work on the 300 GB Hard Drive.
Any Idea what could be the problem? well, I think it could be something related to 'TRIM", right?.
If so, any way I can fix my current OS X on the SSD? I'm almost sure, clonning my successful install of 10.10.5 to the SSD might work, but.... do I need to do something special to that installation before clone it to the SSD?
Thanks in advance for all your help on this.
Last minute Update: It's working now
As soon as I got home, I tried several thing but none work with the Old SSD disk, it never boot again, so, I decided to move on and clone the 10.10.5 working installation (on my 300GB HD) back to my SSD.
First attempt didn't work, I didn't change the 10.10.4 configuration on Mutibeast, so I changed it, unchecked the Trim Enable option and that was it, my SSD boot again now want 10.10.5 and everything is working as before.
