my macbook pro froze so shut it down by holding the power button, now when i try to restart it i get a prohibited sign instead of the apple logo. any way to fix it?
Info:
MacBook Pro (15-inch 2.53 GHz)
My macbook pro, upon start-up, shows the apple logo for a short amount of time then either a prohibited sign or a folder with a question mark gets shown and the computer does not start-up. I have re-installed the OS but it did not seem to work. Any ideas?
Info:

I purchased a game (Broken Sword DC) via Steam and the game runs just fine but the icon in the dock and for the .app bundle has a prohibited sign across it - the same kind you see with a Classic (Mac OS 9) application on Leopard or later. As far as I can see the permissions from the get info are OK the only possible clue is in the terminal doing an ls -al I can can see an @ symbol - which I think has something to do with ACLs?
Any ideas how to get rid of the prohibited sign?
So I keep getting a prohibited sign when I boot up my MacBook pro running Snow
I read it was because a file was corrupted and I need to reinstall Snow Leopard
Well, I inster my Snow Leopard start disk, and hold down C when I hear the chime
I hold it down, I hear the disk in the drive boot up, spin fast, Apple has the progress wheel under it but nothing happens.
I have checked Software Update, and there was two updates. First one was Java and the other one was EFI Update 2.7. I don't remember the Java update version. After I applied the update, the MBP rebooted itself as it should do; but the problem occurred at that reboot. OSX tried to start up three times, like as it was failing to install the updates after reboot. And at the fourth time, after a few minutes the Apple logo turned into a "No Entry Sign".
And it stuck like that. Now, the MBP cannot boot normally, I can only run it on safe mode. I have reset PRAM. As far as I read about the issue over the boards, the problem occurs to be an HDD problem. Yet I can run the OSX in safe mode, which bugs me. So I downloaded SMART Utility to check the HDD. It says there is 1 Pending Bad Sector, and 1 Removed Bad Sector.

When I start my Mac it goes to white screen with flashing apple and stop sign. It will not any further.

have a early 2011 MBP running OSX Mavericks. I use my mac everyday both at home and school. This morning when I opened the mac, the screen was frozen. I simply restarted the mac, and it doesn't go beyond showing a prohibitory sign. I have tried many things..Â
1. Restarted the mac, while holding the Option key (selected Recovery HD), after waiting for nearly 10 mins, the system loaded into recovery disk ( but the twist was, in the disk utility, my SSD was not found/shown)Â
2. Then thought the SSD was dead.. So asked the IT guy to see if he can retrieve the data (removed SSD out of the mac and he used an external hard drive enclosure and the SSD was instantly recognized, saved the data). Here I did two things
   A. First, asked my friend if I could mount his SSD in my Mac and see if the system starts. Even using a different SSD, my mac still showed the prohibitory sign.
   B. Then l installed my SSD into his Mac.. System booted as normal (basically it was all there, but on his Mac)Â
3. So ruled out that my SSD was faulty. Then using the internet based Apple Hardware Test (AHT), I found no troubles with any of the mac components.Â
At this point, I don't understand what is causing my Mac not to go beyond the prohibitory sign? Could it be something as silly as the internal hard drive cable or something more complicated as the logic board? In which case, they should have been detected during the AHT?Â

I turned my iMac on (2008 model) but after 10 minutes it went black and beeped 3 times loudly, repeating at 5 second cycles. Shut it down by pressing the ON button for 5 sec. Restarted and all worked for a hour before repeating the same problem...screen and keyboard and touchpad all locked out....shut down with the ON button. On restart it gave me the 3 beeps every 5 sec with an ALL BLACK screen...no hard disk whirring, either. I don't know how to do cardiac massage on an iMac. Is it dead? Is it the processor? Is it the video card? Is it the hard disc?Â

my 2006 macbook has not been able to start. First it didn't even have the chime, then I read through some threads in this forum and figured out that one of my RAMs was not properly put in. I fixed that, now I get the chime, the apple sign, and a spinning wheel and I am stuck there forever.
I tried:
resetting PRAM, didn't help.
start from safe boot, still stuck with apple sign and spinning wheel.
boot from installation CD by holding either the "C" or "D" key, it would not start from the CD.
Curiously, I can start it in Windows and I am using Windows right now. Some threads said that it could be a hard drive problem, but if I am using Windows, does it mean that my hard drive is fine?
I've already spent 800+ fixing the logic board in 2008 b/c of a water spill and really don't want to spend any meaningful amount of money to fix this 1000 bucks or so laptop. If any hardware is in jeopardy, I'd rather just throw it away. However, I would like to at least be able to start it in Mac OS once so that I can back up my documents.
I've been trying to partition my drives and install Windows on my late 2012 imac. I last adjusted my partitions using disk utility and now receive the prohibitory sign on start-up and cannot boot up in safe mode; pram reset; type commands in single user mode. Running on Mavericks OS.

It appears that I'm unable to sign-in to the App Store. The place is well found under the apple sign and in the dashboard and both respond well to all demands except for the 'sign-in'. None of my other 5 Apple computers render this problem.  The actual computer is a MacPro4,1, Quad-Core Intel xeon, 16 Gb Memory and Boot ROM version MP41.0081.808.

Is there some security phenomenon that will not allow me to copy and paste my PW into the slot/space for Password, when I try and signin to Apple forums. The allocated space where I would normally paste my PW does not show anything being pasted,, and I have also used Paste in the menu area , and even tried dragging my PW into this area, to no avail. Of course, I can type it in manually,, however, my PW is strong,, and generated, and find it very arduous to type in.Perhaps a 10.7 feature?

View 2 Replies View RelatedI'm using the calculator and it uses a comma to separate thousands instead of a point. We use a comma for the decimals, a point for the thousands.The systemreferences says to use a point as thousand-separator, so that's correct.Yet, when I type 23456,57 the result is 23,456,57 while it should be 23.456,57.

I just received my new Mac pro at work and is trying to install Mountain Lion as the OS instead of Mavericks but it seems impossible. Every time I try to boot up on a bootable 10.8 installation drive I get the no entry sign. I even cloned my old MacPro and tried to boot from the external drive, I still get the no entry sign.Â
I tried booting from a thunderbolt, USB and even super drive, with no luck.Â
I need to install 10.8 because Mavericks doesn't work with Active Directory in my company, it just hangs the system every time, we've tried many different ways to fix this but it just seems to get worst.Â
Any way I can downgrade a 2013 Mac Pro to 10.8?Â

I recently updated my Server running 10.7.0 to version 10.7.3 and single-sign-on no longer works for my users. The 10.7.3 Lion Server System is bound to our Active Directory Server running on Win2003 R2 Server. I tried un-binding and rebinding the system but.. no luck. When a user now tries to login to our shares via AFP with SSO credentials they recieve the message Â
I can run the id command from terminal on the OS X server and it is seeing AD users. Unfortunately, no one can log into the server shares via AFP with an AD user.Â

Have just upgraded my macbook to Lion. I logged into the app store, bought, downloaded and installed Lion no problem.
After upgrade I returned to the app store to download ibooks author. I can find ibooks author but when I try and install the app I have to sign in and I get a "connection failed" error message.
The same happens in iTunes when I try and view my account - "The network connection failed"Â
I can access the internet with no problems - including secure sites. I can access software update with no problems.Â
I have made no changes to my network settings - could sign in and download apps before upgrade, unable to after upgrade.
