Anyone know this problem with login screen?

[Bonifant]

Since updating my Macbook Pro Retina (August 2014) to Os Yosemite I experience some small problems. At first my whole Itunes library was gone, I did a re-install of Os yosemite and imported my itunes library but I still experience some small issues. When I restart my computer I got the following screen with my username and all other letters replaced by icons.

Does anyone know how to solve this problem?

Thanks

Hi,

try this : boot in safe mode.

First backup.

Then if you can use something to reliably check the integrity of the physical disk(s) – Disk Utility lacks what's required – make that your second task.

The safe boot suggestion is good, but something about the screenshot, when viewed alongside other symptoms, makes me suspect corruption of data. If so, that corruption may be symptomatic of a problem with the drive.

If you're not inclined to dig deep for an explanation, you can simply backup all data from the drive then use Disk Utility in Recovery OS to erase (or whatever) in preparation for a clean installation of OS X.

Bonifant, you might like to take the problem(s) with iTunes to a separate topic. I now have less of a suspicion of corruption of data …

… installed Yosomite on a macbook pro and on the startup I'm getting X in a box under the icons where the words should be.

I was told by my IT that this was a missing font issue...

see screenshot

any suggestions??

hello anyone managed to fix this issue?

Helvetica Neue or not?

To any person whose Mac is affected: have you chosen something other than Helvetica Neue as the system font?

If so, what's your choice?
