Intel Mac :: RAM Errors Now It Won't Boot
May 27, 2012
My 24" iMac had some graphical glitches and froze up, so I ran MemTest86 on it and got a number of errors reported on my RAM.
I had upgraded from 2x1gb to 2x2gb and kept the old RAM, so I gave that a try. This time MemTest86 itself came up with graphical glitches and reported problems on this RAM as well.
I gave up for the night and the following morning when trying to boot, all I get is the monitor powering up and the Mac boot sound. The system then reboots immediately and does the same thing over and over. Screen powers on (stays black though) and sound plays. I never get to a gray screen at all nor does the Apple logo ever appear.
Trying to boot to safe mode, off cd, single user mode are all unsuccessful, I never get out of the boot sound loop.
NVRAM/PRAM reset attempted, likely unsuccessful.
I've tried booting with 1 DIMM and 2 DIMM across the different RAM I have, but the same thing always occurs. Only time I get different behaviour is when booting with no RAM, and then I just get a beeping tone.

I'm trying to delete my 'serious errors' fonts and 'warning' fonts from Font Book. I have a silly amount of fonts (something like 3500!) and when i select the 'serious error' ones and click 'Remove Checked' Font Book crashes. Well it gives me the spinning kaleidscope mouse working symbol....for ever.

Yesterday we starting getting "Disk is Full" errors on our 1TB iMac. We have approximately 100GB of music, photos, etc., as well as the operating system and Office. It does not seem as if this should fill up the disk. In looking at the activity monitor, it shows that 999GB is in use, with 1GB free (approximately). While I was watching the activity monitor, it went from 1.7 GB free down to 1GB, while nothing was being (intentionally) downloaded. Virusbarrier did a full sweep and returned no threats; spotlight turned up no files added or modified yesterday to help identify where the space is being used.

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

OS X 10.4.3 IMAC Intel Core Duo. I backed up my HD on an external drive so I could upgrade to Snow Leopard. I wanted to test that I could boot from the external drive and selected it as my start up drive. When I did a restart I got the Apple and the turning gear and then suddenly a black screen with this on it:
"May 28 22:23:11 Launched:com.apple.nibindd:respawning too quickly throttling, exited system abnormally bad system call too many failures in succession I have no name!"
I tried several dozen times with no luck. I think when I made the copy of my HD on the external HD I may have neglected to make it "bootable" (moving too quickly). My internal CDROM is busted so I use an external CDROM. I can't boot from it at all with the proper start up buttons pushed. It keeps trying to boot from the external drive. If I turn the external drive off and try to boot from the external CD I just get the grey file with the ? in the middle of it.
I tried using another external HD I have with OS 10.4 on it, but it won't recognize it either with fan, alt, shift, delete pressed at start up. My internal drive (a Seagate 2 tarabite drive) works great, but how do I reset it as the start up drive when I'm stuck with this black screen. One more thing, when I try to reset PRAM I don't get a second gong.

My iMac was working perfectly till two days ago, I shut it down normally, but haven't been able to start it since then. When I press the start button I can hear the HD and fans working, and also the USB ports are powered, but screen keeps black and no boot tone.
Since I have a bluetooth keyboard, I am not able to start in safe mode..

I just got my MBP yesterday, and so far it's been incredibly frustrating. Trying to download Firefox, 3 separate times, I get "image corrupted" errors when I try to open the .dmg. This is probably the 10th+ time it's happened today errors ranging from "invalid checksum" (from Facetime, downloaded from Apple), to "error -199". Any ideas what's going on? The same things appear to be just find on my Mac Pro, and they're running the same software. Already ran verify/repair disk multiple times.

I've just done a fresh install of Leopard to see if it would clear off some of these permission errors. Does anyone have any suggestions? I've tried OnyX, booting off Install CD.

A lot of these errors keep "polluting" my Console daily. I've reset Dock, but nothing changes. What are these msgs all about? I've had these for long time (possibly even in Leopard - I don't remember exactly).

I recently bought a hard disk drive for my macbook - specifically an internal, 500GB disk with 32 MB cach�. I installed OSX without any problems, but lately I've noticed some programs start doing funky things (Finder getting stuck frequently for no reason, once even the settings panel got stuck, svn weird behaviour complaining a file is both non-existant, locked and not versioned, etc.). Just out of curiosity I tried checking the disk with the disk utility and it found filesystem errors.
I heard some rumours a few years ago that disks with big cach�s required a bit more time before shutdown to committ everything to actual disk.
These errors and funky behaviour *seem* to appear when I reboot so I'm suspecting the rumours might be true. What do you think? Anyone out there with a big cach� HDD? should I try exchanging it for one with a smaller cach� or is there any setting I can access for this case? Or maybe is it simply defective?

I had a 320gb hd drive in my mbp that was running out of space. So I ordered a 750gb drive to replace it. My mbp is partition 25% Mac 75% Windows. I used Carbon Copy to clone the Mac side of the drive to the new drive.Then placed the new drive in the mbp.I then used sys utilities to partitions the new drive 25% Mac & 75% windows. The I downloaded Winclone to the Mac side and attempted to make a image of the old bootcamp partition. I selected to save it to an external drive that is formated for Mac.
About 80% in the Winclone stopped and said Errors Found see logs.Tech support can't figure out why it's not making the image.Then they suggested I turn off the screen saver. So that's where I am not.

Three days ago a noisy fan brought me to the Genius Bar at my Apple store and when i got there the boot screen stayed gray and had a folder with a question mark in it. I have a late 2006 15" MPB running Snow Leopard 10.6.6. The guy told me i need a new hard drive so i went out and bought a Western Digital Scorpio Black 320g 7200 rpm SATA drive with a 16 mb cache. I replaced the old one with it, formated and installed OSX 10.6. I then used my time capsule to recover my last back up. I completely restored it. TWO DAYS OF PERFECT USE Now, i have the annoying fan noise again and my console is telling me that my HDD is having disk0-02 i/o errors. A LOT OF THEM. I've had at least 30 before noon today. Currently i am writing zeros to my drive and going to reinstall 10.6 WITHOUT using my time capsule restore (incase that has bad blocks written to it) Has any one heard of issues like this before with the particular HDD i bought? Two HDD failures two days apart seems fishy to me, what other issues should I be looking at? Is it possible i'm getting the i/o errors from a bad HDD ribbon cable to the logic board?

I'm running 10.5.7 on my MacBook Air and while browsing the Console System Messages I came across the following lines which seem odd.
I have tried to understand what is going on and validated all my fonts using FontBook with no errors. I have not installed any fonts apart from those that come with the system and iWork 09.
I presume that these messages should not happen as they are errors and must be the result of something being wrong.

Girlfriend just got a new iMac all in one a week or so ago. We had no problem setting this up on the exsisiting network but a couple days ago we began having issues. The 3 PCs, 2 iPods and one network printer seem to connect fine until the iMac connects (or tries to). We've gotten IP confilct errors on various machines (assigning already assigned IP address). I cannot even connect to the router when the iMac causes this problem. Take the Mac off, everything runs fine. I am new to the Mac world so maybe I'm missing something. Here's what my network consists of... Scientific Atlantic DPC2203C cable modem (Optimum) Netgear WGT624 v3 router 1 iMac all in one, 2 HP and one Gateway PC(all Vista), 2 iPod touch, 1 HP wireless printer all running DHCP and wireless.

my 2.4ghz 3 year old macbook pro is experiencing a lot of graphics errors and lockups recently, where the screen will turn garbled and such and the computer will freeze. Keep in mind this is the 8600m gt. However, I just got the nvidia fix done for free by apple a couple months ago. Is it possible it could be the same problem?

I am attempting to fix my gf's Macbook Pro w/ 10.4. She had tried to reinstall the OS a few weeks ago, and I think the installation was bad.
So, her computer ended up not booting, and just sitting on the start-up screen.
I decided I would try a full reinstall, with formatting and everything. I backed up her files, and could not get them to delete from her harddrive using my computer (when linked via firewire). So, I booted from the disc, erased her drive, and formated in Extended Journaled.
I tried to install the operating system, on what I assume is a clean harddrive, but about halfway through, it keeps failing. I went into disk utility, and the harddrive says "verified" in the S.M.A.R.T section, but whenever I run verify, or repair, I get an error message saying "Could not unmount disk".
I searched the forum, and there are topics concerning this message when accessing disk utility normally, but nothing about this message appearing while running from the OS disc, on a fresh harddrive.
I have tried everything I know of (which is not much), with no success.
Could this error e the cause of OS installation failure? If not, the only other thing I can think of is that the actual dvd is bad, but it looks fine to me.

For some time now I have had problems downloading files/programs from the net. Things like OS critical updates; Adobe updates; VMware trial software; games; virus definitions. The download run into problems when unpacking - most common error is that verification failed but there are also failures in unzipping files (NAV installer being the most recent).
I have checked a number of forums and found similar problems but none seem to work (eg. mounting from disk utility). The only thing I haven't done is reinstall from OS archive disk as this could entail reinstalling a lot of things (mind-boggling).
I have a MacBook (2GHz Intel Core 2 Duo with 1 GB 667 MHz DDR2 SDRam) running OSX 10.4.11 and also have Parallels 3 (build 5608) running Vista. The download problems seemed to begin with updating the Parallels software. I received the verification error or a checksum error. I resolved this problem by using different download sites. When investigating this problem it was suggested that the ISP provider was at fault. Is this possible?

My son is trying to open a .jar on his Macbook to add a mod to Minecraft. It throws an error and directs him to Console each time, but Console isn't showing any errors. Using advice on a couple of similar threads I followed some steps but ended up at a dead end.
The Terminal message I get when I follow the steps in another thread is this:

I am trying to download updates on my MacMini. Every time I try I get a message that says "Mac update cannot be saved you are not connected to the internet." but I am always connected to the internet. Sometimes I get other error messages, but I can't remember what they say. I have a Mac OS X 10.7 and it is trying to download Mac OS X Update Combined version 10.7.3 and Java for OS X 2012-003.
I should mention that I am also having trouble backing up on time machine. Though it works when I hook my external hard drive. A few months ago I was having some issues with my computer so I whiped it clean and I think somewhere in the process things got screwed up. I don't know if any of this has anything to do with why I can't update my computer.
