Apple symbol replaced by circle and slash symbol?

I attempted to wake up my sleeping Macbook Pro, but becomes unresponsive. I go through all the regular steps to get it to respond, but finally reboot. It starts to boot, then replaces the apple with a circle and slash symbol. Thoughts?

See if this will help:

How to start up laptop from grey screen with circle and slash through it?

After you installed Yosemite and prior to restoring from the backup, were you able to start the Mac?

MacBook Pro has a grey screen with circle and slash and will not start up or start into safe mode.

MacBook Pro has started to get a grey screen with circle and slash and will not start up or start into safe mode. This happened once previously, however, it allowed a safe mode reboot and then worked for a week or so. While utilzing the machine, it started with the spinning beach ball for about 5 minutes, went into a shut down mode and then rebooted and came back up with the grey screen with a circle and slash after a few minutes. For the past three days it has been stuck and will not allow it to boot into safe mode. Any idea or suggestions?

Try starting the MBP with the OPTION key down. If you see two HDD icons, select the recovery Icon. From the 4 option menu, select Disk Utility. Select Disk Utility>First Aid and run Verify and Repair.
If you cannot get into the recovery partition, make an appointment at an Apple store genius bar.
Ciao.

My Mac has been randomly shutting off. Apple recently replaced my battery, and then performed several diagnostics tests on it. After replacing the battery, they said that everything passed.

I evaluated the internal temp (using Istats pro) and it is at 86.5 degrees feh (about 22 c*). Is that normal? What tools can I utilize to ensure that the internal system prevents from overheating. I have the Mac running on a cooling fan.

AS Ralph indicated, the system does not allow for that.
B.) I will post the Istats screen when I get home from work.
My concern is that the temperature you reported is abnormally low. Thus I would like to see an image of the temperature monitor. In sounds more like Centigrade.
Also post an image of Activity Monitor showing ALL PROCESSES and % CPU displaying values from high to low. This way we can determine if the temperature readings reflect the activity being performed on the MBP.

When I try to downlaod Firefox it comes up with a circle with slash across it and won't downlaod.

I have used Firefox for years. Now it sits in my dock with a circle and slash across it. I'm not even sure how it got that way. I have tried to delete that icon and redownload Firefox and it ends up looking the same way. I am on a Mac with OSX 10.5.8 - 2 GHz Power PC G5 processor and 1GB DDR SDRAM memory. How can I download a usable version of Firefox again? Thanks for your help.

Circle w/ slash at boot; won't boot DiskWarrior; won't acknowledge OS 10.5

I have a Macbook which suddenly started booting up to a circle and slash symbol, and refuses to go any further.
There were a number of detailed threads about this on the forums, but none of them seemed to fit my particular situation. If anyone has any advice regarding the following, it would be very much appreciated:
I tried repairing the hard drive via DiskWarrior 4.1, but the Macbook refuses to boot from the CD. I can boot from my OS 10.5 DVD, but I am unable to run Disk Utility, as the application sees the Macbook's hard drive, but will not allow me to actually select it in order to verify or repair it. In addition, I have booted up the laptop in Target Disk mode, but my G5 tower fails to see it; however, my tower does acknowledge when there is a CD in the Macbook's drive (such as Disk Warrior or the OS 10.5 DVD).
Lastly, I tried to do an Archive & Install via my OS 10.5 DVD, but when I do this, the install application informs me that it is unable to find OS 10.4 or newer on the hard drive. (The only thing I can't remember is what version of 10.5 the laptop is running, although I update the laptop frequently.)
Anyone have any thoughts? I'd love to try and fix this myself before running to an Apple store.
Thanks,
Will

Start here: Mac OS X- "Broken folder" icon, prohibitory sign, or kernel panic when computer starts.
If a kernel panic is involved visit The XLab FAQs to read the FAQ on diagnosing kernel panics.
You can try this:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
This will not likely get the computer to start, but it would confirm if the drive is OK or repair the directory. If you can then gain access to the drive via Target Disk Mode then you may be able to recover your files. Then use DU to repartition and reformat the drive. If the drive cannot be repaired or reformatted, then it has most likely failed.

Start up problem: Circle with slash sign in it

Hi,
Just recently had this problem. Before this happened, I have installed the 3 updates from apple, uninstalled my Norton Anti Virus program and installed the Intego Virus Barrier, Net Barrier and File Guard X5. Just discovered this problem when after installing the Intego Software, I was instructed to restart the computer to complete the installation and then, the circle and slash sign appeared. So what I currently do to access my laptop is to start up using the safe mode, shutting down and starting up again as this process lets me complete the logging procedures and avoids the circle/slash signs. But after I shut down, the circle and slash sign would appear again on the normal start up procedures.
Any ideas on this? Help is most appreciated.
Thanks!

Thanks!
It was the Norton Software which has not uninstalled all of its hidden components. Already did the full installation. For anyone having this problem, see the full link of the thread below on how to uninstall the Norton Anti Virus.
Hope this solves your problem too!

Whenever i start my macbook pro the screen remains gray with the apple symbol and the circle timer below. The screen stays this way even if i leave it for hours.

When i turn on my macbook a box appears telling me i need to restart my computer (in different languages) and in order to do so i have to press on the off button for a lil while. Even after doing this the same box appears and it never restarts correctly. This box appears every single time. I rarely turn my computer off. I just place it on sleep mode and restarts it only when i get prompted to. I brought it to genius and they couldnt figure out what the problem is so i was told it needed to be shipped to get fixed. I didnt have anything backed up. All i want saved are the pictures because i went to 2 events where i was the assigned photographer and i didnt get to save it to an external memory. Genius said that when shipped i cant give instructions like make sure to save the pictures and if they are unable to, call me if they should go on with the process. I was wishful thinking that to fix the problem they might not even have to touch the pictures memory part. I brought my MBP back home hoping it will miraculously starts and id be able to back it up but now all it does when i turn it on is the screen remains gray with the apple symbol and the circle timer below. The screen stays this way even if i leave it on for hours. Please help me fix this!!! cant i really specify to the technicians at apple to please make sure not to erase the pictures? Is there no other way to turn on my mac? I only need it to work ones.

Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
In other words, your computer can't talk to your operating system so you can't access your data.
Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
First: Shut down your computer completely
Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
Hope this helps, it's annoying but it's your safest bet.
All the best.

OS X v10.6- Gray progress bar appears under Apple logo during startup
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Start up problems, get the circle with slash symbol then hangs forever

I did a bad thing, I downloaded some software from the Internet. It was from Smith Micro. After the first re-start after installing, I had start-up problems with the "not allowed symbol" (a circle with a slash through it) coming after the Apple symbol then hanging forever.
The Smith-Micro programs I down loaded were Spring Clean-up and Internet Clean-up. I have not used either program, just installed them.
I have run Disk Utilities from my start-up disk, everything tested out perfectly. Tried a Safe Boot, computer started up but I couldn't do anything (useless for me). Tried to Zap P-RAM, didn't work. Tried booting in target mode, got a weird symbol ( can't even explain this one) and it just hung there. Unconditional reboot works, and I can use the computer like normal. Does the unconditional boot mess anything up. Should I use it from now on?
I used the included uninstaller for both Spring Cleaning and Internet Clean-up, the computer still won't start-up normally.

There's hardly any circumstance that requires the so-called "clean" install; it's a windoze-centric thing. Just reinstall, ensure that fixed the issue, then run Software Update. Snow Leopard's installer only replaces the OS components and basic Apple apps, such as TextEdit, Mail, Safari, Terminal, and Calculator, leaving *everything else* in place. In the future, always make a restorable backup before installing new stuff.

Couldn't get to the login scrn. Circle with slash symbol. S-mode not helpin

System: *PowerMac G4 DDR 1GHz with 1.25GB RAM and Tiger 10.4.10 (or .11 not sure)*
At first, I could not get the Mac to get to the login screen i.e. it boots up but the timer symbol thing (you know that clockwise 'loading' icon thingy) keeps cycling for hours (eventually I switched it off not to waste electricity).
Tried second time using OS X install disk and check + repair disk, then boot up - still the same symptoms. (NB. Looks like I can do the fresh install though but that is not my intention just now).
Then, did the reset PRAM thing (cmdalt+PR), second chime - folder/question mark (no startup disk screen), then it shows the circle with slash icon on screen, eventually shut it down.
In single user mode, it stops after the 'got bootdisk...' and no flashing of the keyboard cursor.
In verbose mode, almost the same as above.
+Have not changed the PRAM battery or reset PMU. Have been off the grid (off at socket for quite a long period but does not normally do this).+
+In single user mode, one of the line says clock is wrong or reset. After PRAM reset, one line says PMU was reset.+
My questions are:
1. What is that circle with slash icon mean? (can only find on Intel Mac pages - could not load boot.efi, or some other issue)
- ref: <http://support.apple.com/kb/HT2674>
2. Is installing a new system folder the only solution?
3. Do I need to get a new battery?
4. Is my startup hard disk at fault?
Thanks.

Hi Dean,
Have been off the grid (off at socket for quite a long period but does not normally do this).
I'm pretty sure the battery is extremely dead if the computer has been off the grid. Remove the PRAM battery and see if it starts. A new battery is always a good place to begin. We've seen plenty of posters here say their MDD startup problems cleared up with the installation ofa new battery. I get my batteries here:
http://eshop.macsales.com/item/Newer%20Technology/BAA36VPRAM/
I don't know your geographic location; if you are not in an area served by the above reseller, you can use the specs in that link to shop locally. Bottom line--you need to eliminate the battery as a suspect before proceeding with troubleshooting.
If a battery is over a year old I don't bother testing it. I've had too many PRAM batteries test 3.6V in my hand yet did not perform well enough under load to propelr work in teh computer.
Another easy thing to try is a Safe Boot. Info here:
http://support.apple.com/kb/HT1455
Be sure to give the computer time to get to a desktop--takes longer is safe mode.

Try restoring the iPhone to factory settings. If you are having difficult restoring, put the iPhone into Recovery Mode and see if that then works:
http://support.apple.com/kb/ht1808
If not, or if a restore to factory settings does not fix the problem, then your iPhone may have a hardware problem. You can only get the iPhone serviced by Apple in Canada, so you will have to take the iPhone there or send it to someone you know in Canada who can get the iPhone serviced and send it back to you. The only option for getting service in Pakistan would be to pay some unauthorized repair shop to attempt a repair, after which Apple will no longer provide any service even in Canada.
Regards.
