How do I get rid of random screen flicker and black screen when using a late 2013 Mac Pro with a 4k Samsung 55" Display?
I have a new Mac Pro late 2013 and a 55" 4k Samsung display connected using an HDMI cable. For the most part the display is amazing, however, I get occasional screen flicker and black outs. Can anyone help? Could I possibly have a bad video card?
4K displays take more than half the bandwidth of a ThunderBolt Bus. So you may get better results if you are careful to place them on their own Bus. This article has the explanation of which port is using which Bus:

Just updated the latest Epson software printer update from Apple. Now all my prints look solarized. How do I get rid of the new update and go back to the perfect prints I had before? Help please. Wasting ink and paper at the moment!!!!!!
I have tried the printer with my laptop (not updated) and everything is fine. It's just the beautiful 27" Imac that can no longer print.Might be a corrupted printer preference file ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Preferences
Click Go
Move the com.apple.PrinterPrefs.plist file from the Preferences folder to the Trash.
Restart your Mac, restart the printer... -

OR...
You could use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

How can I get rid of duplicate birthdays in icloud Calendar, especially when there are no Contacts in the iCloud? Case ID: 365381395
Found the answer myself while helping to set up iPhone. It is simple when you know how. Before signing out of iCloud to sign in again and restore the link to Photo Stream I had opted to copy iCloud contacts to the Mac. When I signed in again this created two iCloud views which can be seen in Contacts Preferences. I just disabled one of them. Not brave enough to attempt removal but I gues this would work too.

I have a huge amount of my memory used by 'other' than photos and music - to my knowledge, there is nothing there apart from a few songs and photos and 5 podcasts. What could it be? How could I get rid of this 'other' stuff and get the memory back?

Error 404 - how do I get rid of this message on my Google page when I open Safari?
How do I get rid of error 404 on my Google page when I open Safari?
Safari - Reset Safari - choose all options and reset Safari.
If that does not work then check to see what Safari extensions you have installed, one or more may be creating a problem.
Another possible fix is restarting in Safe Mode which clears some caches, one or more may have become corrupt. To restart in Safe Mode simply hold down the Option key when you hear the startup tone until a progress bar appears. Then test Safari and then restart normally. -
A magnifying glass and search box show up in my e-mails and I can't read them unless I hit reply or forward. how do I get rid of the magnifying glass and search box?
First, some clarification:
* The location bar (often called the "awesome bar") is the larger bar on the left that shows you the address of the page you are currently viewing. As you type in the location bar it searches your history and bookmarks for matches.
* The search bar is the smaller one on the right. It typically displays an icon of whichever search engine is currently selected and may display search suggestions as you type in it.
It sounds like you are referring to the search bar rather than the location bar. You can change search engines for the search bar by clicking on the icon on the left edge of the search bar and choosing a different one. You can also choose "Manage Search Engines" to remove ones you aren't interested in using.
It also sounds like Bearshare might have changed your homepage in Firefox. To restore that you will need to open the preferences menu (click Tools > Preferences), go to the General tab (first on the top left), and click "Restore to Default". -
