OS X :: What "chmod - R 777" Command Does - (trying To Fix Blue Screen)
Sep 10, 2009
So the code is: chmod -R 777 / I was following 'instructions' from this random thread I found trying to fix my g/f's macbook running 10.5.8 - it just sits at the blue screen at start up. thread: [URL] I followed the instructions in post #8. Is that a legit fix or is that guy messing with people and I screwed up her computer? Anyway it didn't work - still a blue screen - guess I'll just tell her to go see a genius.

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

Sorry, really not a computer buff. Only learn what I need. However, I'm trying to install a program on my linux host and it says that I need to CHMOD a document to 777 in order to have it work. If I can CHMOD on OS X how to do that?

I'll have to provide some background info so you know what's going on. I'm setting up a preconfigured .conf for Viscosity (OpenVPN). What my sh script does is copies all the pertinent files to the correct folders and runs sed to customize it for the particular user. Normally you'd just chmod +x it to make it executable..in this situation EVERYTHING needs to be rolled up into one click as this will be distributed to 'uninformed' users and needs to be foolproof. I've tried "sh->app" rollers such as platypus and they suck and only run half of my script at best. So experts, I Ask, how does one make a self-contained, executable .sh script that can be distributed and executed on multiple computers without ANY user intervention beyond "download this and double click it"

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.

I have a problem with my MacBook screen. Everytime I try to turn on the MacBook, the blue screen appears for a second and then everything gets dark (but I can see that the computer turned on normally, it's just the screen that gets almost black, without light). Sometimes only the right side of the screen is blue and then gets dark just like the left one. I was looking for the problem and I perceived that the left side seems to be loose and I can't fix it. What should I do?

grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced <6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen. Then tried the other way (I think it's command alt delete? I don't remember) and it turned from grey (no apple symbol) to blue blank. Then third time, grey followed by blue with vertical lines, not blocky clear lines that you can see if you are close to it.

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.

iMac (27-inch Mid 2011)

I just meant to do one folder, but I accidentally did it all, including Library. Is it okay to have Library as 777 or should it be something like 755?

I use "Ctrl+Shift+Eject" to shut off my iMac screen (not shutdown) usually before I go to sleep, but recently, I've had to hit it 5 or 6 times before it actually turns off the screen. It also happens when putting the computer to sleep pressing "Option+Command+Eject".

All of a sudden, holding down the Command key for more than a second or two (e.g., in preparation for using Command+W) brings up a Universal Access dialogue screen which fills the monitor. I have not used Universal Access, I checked the settings, and I see nothing seems to be "On".

When I restart the mac with the command "reboot" of the finder. I have a gray screen and nothing more. If I use the command "Turn off" and I turn on the mac by the start button it works.

I saw this little "trick" command, control, alt, 8 in a Mac article a few weeks ago. It was nothing more than a cool, little screen alteration that makes the screen go negative. I tried it after first getting my Mac. Just this past week, I tried to do it again and it is not working. Not that it is a serious issue however it is more of a curiousity why it stopped. Did some application I installed on my machine cause this feature to halt? Just curious if anyone has the answer. I tried disabling Shades, Growl and even turned off my power settings to see if that was interfering.

I know yall probably get this a lot but I am having a lot of trouble rebooting my macbook. A while ago I was using my computer and all of a sudden it froze I then tried rebooting with the start up disk and was successful and everything began working fine again until all of sudden my mac just froze. I powered the mac down and i wouldnt turn on, so I tried to reboot the system again and everything was going fine the computer was installing all the software so I left it going overnight for Disk 1 to complete, when I woke up all I saw was a blue screen with a white box saying MAC OS X and under a blue bar with "starting Mac OS X" underneith. I then powered the computer down and redid the apple, option P R to reset the Ram again but I still get this blue screen that I cant get past. I have read about booting the computer up in safe mode and i tried that but that didnt seem to work.

I just installed the graphic card and when I turn on my Mac I get the Apple Logo and the spinning progress wheel and then the screen turns blue for 5 mins and then turns on. The tech at OWC said that it is normal to do that the first time but should speed up after the subsequent restarts, etc. Well, it is continuing to take 5 mins to start up.
Here are some screen shots of my Graphics card info and then another shot thats drivers installed YES and drivers installed NO. Is that correct?

I've had a MacBook for about four months, completely standard version, no modifications, no nothing. It's been working perfectly. I've the latest version of Leopard and any other software update that comes with. Today I've been working on setting up a new user account entitled "Work" - for obvious purposes. I've copied my regular account's home folder as well as applications and such to make "Work" as much of a copy of my regular account as possible - let's call that account "Me".
And so I've mostly been browsing around "Work" trying to give it the same access to files as "Me" has - "Me" is an administrator, "Work" is standard - by changing access and privileges. I had some problems getting "Work" to save - when I would log out and then log in again, "Work" would have lost the preferences, e.g. Stacks and Dock settings. I also couldn't change the desktop picture for whatever reason.
So then I was going to log out "Work" to see if it still had the saving problem, and it lagged behind a lot, so I did the emergency-turn-off-by-holding-down-power-button-that-you're-not-supposed-to-do thing. And then when I tried to restart, it wouldn't............

I am running OSX 10.5.7. Installed it several weeks ago. This morning, the computer was acting up a bit. For instance, in my wife's account, I couldn't access our shared iTunes library, getting the error saying it was locked. When I rebooted, suddenly I couldn't get into the machine. It just hangs on a blue screen. I've tried booting with the shift key down, and that didn't do anything. I also tried cmd-s, but don't know what to do with that at the prompt, and cmd-v, which works fine, but just dumps me into the blue screen again.
I have a bootable FW drive, and I can boot fine off that, and even see the internal drive. I've opened files on the internal drive -- it all looks intact. But I still can't boot from the internal drive. I've tried Googling for solutions, but if you google "hangs on blue screen" or bsod or whatever around OSX, you get a bunch of hits related to installing 10.5.7, which isn't my issue, and you also get articles from 2006 and 2004, etc. I was hoping it was some sort of permissions thing, but I am not really sure.
