Minecraft Forums

So I am playing on a Mac and when I open up my Minecraftlauncher, the small code/text window that usually says something like:

Bootstrap (v5)
Blah
Blah
Blah
Finished
Launching Minecraft

will say:
Bootstrap (v5)
Current time is Mar 10, 2014 8:46:39 AM
System.getProperty('os.name') == 'Mac OS X'
System.getProperty('os.version') == '10.9.1'
System.getProperty('os.arch') == 'x86_64'
System.getProperty('java.version') == '1.6.0_65'
System.getProperty('java.vendor') == 'Apple Inc.'
System.getProperty('sun.arch.data.model') == '64'

Looking for update

Reversing LZMA on /Users/Jack/Library/Application Support/minecraft/launcher.pack.lzma to /Users/Jack/Library/Application Support/minecraft/launcher.pack
Unpacking /Users/Jack/Library/Application Support/minecraft/launcher.pack to /Users/Jack/Library/Application Support/minecraft/launcher.jar
Cleaning up /Users/Jack/Library/Application Support/minecraft/launcher.pack
Starting launcher.

And then it will bring me to the login screen but when I try to log in it says:

Sorry, but we couldn't connect to our servers.
Please make sure that you are online and that Minecraft is not blocked.

I just recently had my computer repaired and it was working perfectly before and now it does not work. Please help.

I am not sure but I will look to see.
