First off I want to say I've been looking for answers for this on google for a few days, and I've found similar problems but none of the fixes have seemed to help me. Then again I may be doing something wrong. I've recently purchased a 500GB Momentus XT to replace the stock hdd in my early 2011 mbp 13".Originally placed the disk in an external usb 2.0 enclosure and made a clone of my the stock disk. I could boot fine from the momentus xt when being run from the enclosure.
Problems arose as soon as I tried to swap the drives around. Now I could boot fine from the stock drive (in the enclosure) but the momentus XT could not be booted from. I tried swapping the momentus back to the enclosure, and it still worked fine this way. I attempted to reset PRAM and Smc, and it didn't help me.
So I tried to reformat the drive, and to make a partition of 495.11g with the rest being empty space (I read this may help). I then put the momentus into the internal bay, in hope of booting osx from the original disk over usb, and migrating the data I needed over. Disk utility could not recognise there was even a disk in the internal bay (the momentus), just as before.I tried updating to lion (I was on snow leopard before) and turning it on again, but still disk utility couldn't even recognise the presence of the momentus xt when used in the internal bay.
I have noticed that I am having trouble updating the EFI firmware to version 2.7. Every time I try, it runs through the installation, restarts, says install was complete. But when I go to system update, it still lists this as an update, and system profiler still says I'm on the older version. Yes, I have tried updating it using the package from the apple website, it is no different.

My Mac book pro would not boot up. Only trouble I've had is it was getting slow to boot up I tried to reinstall OS X is it didn't show my hard drive. I put in a new 750 gig Western Digital and went to install OS X and I have the same problem I go to install and on the screen that you choose your hard drive it s
Doesn't show up. I went to disk utilities and only my DVD drive and portable hard drive shows up.
To provide some background on my issue, my portable hard drive format was NTFS, and I wished for it to be FAT-32.¬† I was trying to transfer some files over from my Windows computer to my Mac, however it wouldn't work due to the formatting.¬† To change the formatting, I used some third-party software and started the conversion (without formatting the drive so that I could keep all my files) however mid way through the process, my stupid laptop entered sleep mode and stopped everything.¬† ¬†
When I tried to re-plug the hard drive in my Mac, it didn't show up in the finder, but the Disk Utility did find it.¬† The model I have is the iStorage DiskGenie portable hard drive.¬† ¬†
I am going to buy a used MacBook Pro from a friend. The internal hard drive doens't work so they have OSX running from an external hard drive. I want to replace the internal hard drive with a new one but the person I am buying it from says that the Conection between the Motherboard and hard drive is messed up. Is there a connection between the Hard drive and motherboard that I can replace?
On start up the white screen of death and a flashing file icon with ? is all that happens.
Have reset PRAM and SMC
Boots perfectly from external drive
Internal drive is ok, in fact I have tried two different drives both of which are working perfectly.
Doesn't start in Safe Mode
Starts in Single Use Mode¬†¬†

I just recently installed an internal seagate ultra ata 100 80gb hd into my powerbook g4 (the old one crashed beyond use). I hear the drive spinning when I boot up the computer. However after the computer boots up with the original boot disk that came with the computer and I try to format it using disk utilities, it does NOT recognize my hard drive (e.g. the hard drive doesn't come up on the list of drives to fix).
My little brother bought an old iMac G4 off eBay about six months ago, against the recommendations of my parents and I who told him he should save until he could afford a slightly better machine. He's been improving it here and there when his savings from lawn mowing and birthday has allowed and his latest investment was the 10.5 operating system. When we went to install on the G4, my brother was shattered to find that the machine wouldn't support it. I investigated and found the problem was due to the G4's 800mHz processor. Not a component he could easily switch out. So after a quick flick around, I found another G4 that I considered could actually be a legitimate investment, given the parts we had. The seller claimed that it was perfectly fine, only lacking a working optical drive and hence, also an operating system. Both of which we had.¬†
The second G4 arrived last week and I successfully switched the working optical drive from the old G4 with the "broken" one. Just to make sure I wouldn't lose the screws holding it all together, I installed the "broken" optical drive into the old G4 as well. Then I went to install Leopard. The new G4 has a 1GHz processor and it recognised the Leopard install DVD at boot. It presented the loading screen with the Apple sign and the rotating loading wheel, but wouldn't progress past this. Every time we tried to boot from the install DVD, it would present this screen for around a minute and then the Apple sign would be replaced by a prohibited sign. The booting process never got any further than this. I talked to a few people and ended up installing Leopard via target mode, assuming there was something a little sus with the harddrive which would be resolved once the OS was in place. But wherever the problem lies, it still remains. The G4 now boots successfully from the harddrive and operates fine, but refuses to recognise the optical drive. Here is my chain of reasoning:¬†
- The optical drive in the G4 is not at fault. We know this because it operated fine in my brother's first machine.
- The hard drive is not at fault. We know this because the OS installed and now boots and operates without problem.
- The OS is not at fault. We know this because I performed an almost identical installation (minus target mode) using the same install DVD only days before on a G5.
- My installation work is not at fault. We know this because I performed an identical installation of the "broken" optical drive in the old G4. An interesting side note: the "broken" drive is working fine in the old machine. It is not as broken as the eBay seller thought. ¬†
I don't know a whole lot about computers. Most of what I learn is from trial and error problem solving like this. My question is: where does the problem lie?¬†¬†
I have a white macbook. I went on holidays and when I returned,the battery had and x through it. It wasn't plugged in. I try and check the cycle count, but since it doesn't recognize the battery, it won't say.
my GF and a glass of Wine. Cat hits wine and wine hits MBP. The Mac shut off instantly, we acted pretty quick and mopped up and turned upside down. I then took back off and over the course of the next 5 days I have stripped it down completely including the Key board and cleaned as best as I could. I've put it all back together and it starts up, a reassuring tone rings out, then apple sign appears with a loading bar beneath, this takes a while then it reaches the Lion log in page.It still recognizes me, or rather my name as the user but refuses my password which I know is correct.The keyboard isn't backlit but keys are typing something (can't see characters, just dots).¬†Screen brightness works.No back light on keys although this may be normal at this point, not sure.¬†
My macbook doesn't recognize my new modum. I have to select it every time I log on and then comfirm the change by imputting my administrator's password. How do I get it to recognize my network as "preferred"?
a few days ago, something weird happend, my 15" macbook pro just stop recognizing the internal speakers or the headphones, just died.The icon in the menu bar is low gray and do nothing the volume buttons appear with a forbidden sign I dont know wath to do?
my mac book pro is not recognizing my WD 500 GB external hardrive. I checked and double checked to make sure the external was mac compatible before I bought : and it was. It also is not recongizing an WD external hardrive I borrowed from a co-worker.¬† Here is what I have done and checked so far.¬†
- I checked to see if the externals worked on other Mac Pros( just to double check mac compatibility)-¬† they showed up on on 4 different Mac books.
- I checked to see if¬† there was something wrong my usb ports. So I incerted my 4 GB flash drive in the USB port, and then my co-workers 4GB¬† Flashdrive-¬† My computer recognized both the devices.
-¬† My computer was very full ( that is why I bought a bigger hardrive to back up my files) so¬† I thought¬† maybe there just wasnted even enough free space for my computer to recongize the devices. So I freed up 70GB of hardrive space on my mac book. - still nothing.
- I also checked to make sure¬† I had the suggested software updates to run the drive, before I bought it.¬†¬†
I have an HP printer hardwired to my iMAC and have been sharing the printer, wirelessly through the home network, with an older Powerbook G4. I've added a third laptop (Mac Pro) which also shares the Wireless network, but can see the Printer online. I get a message that the Printer is not Online.
why the third laptop can't see the printer online?
I just bought 2 - 4 gb memory to ugrade my 2 - 2 gb memory on my macbook pro 13" early 2011. Installed them and rebooted. The About Mac still shows 4 mb memory and looking farther it shows it has 2 - 2 mb memory. Also, now when I close the lid on the computer and it shuts down completely and not just go to sleep. i do not know if the two are related.
I started having problems with Yosemite and lion (installed in the same hard drive, different partitions) so i erase all and instal mavericks, the macbook is late 2009 stock but i don't have startup disk, when i install mavericks it tells me that wont boot and it went an error trying to install, so i am able to boot with the alt key but my mac doesn't recognize de boot disk, when i try to select the startup disk on preferences it tells me: "You can‚Äôt change the startup disk to the selected disk. The bless tool was unable to set the current boot disk.", what i can do, i can boot with the alt key but it doesn't boot automatically.
so just like the title says I'm having some trouble as I did a recent upgrade to snow leopard and I have been beach balling a lot. I read that I should do a fresh install and heres where I ran into problems. My external HD is not appearing in finder. It used to work just fine before and it works fine on all of my roommates macs. I tried rebooting to see if it would fix the problem and all that happened was it made my bluetooth module say it was unavailable. Anyone have any ideas on what to do?
My shiny new Macbook Pro has already had a logicboard (Mac-ish for motherboard) replaced due to this.¬†Games (tested Battlefield Bad Company 2 and GTA IV) crash within a few minutes with the screen freezing and showing random colors as the sound starts stuttering and the only solution is to do a hard restart - see image below.¬†GTA IV tells me that it only recognizes 60 MB VRAM so I guess that the problem is with the graphic card not being able to use the computers onbard RAM (8 GB Corsair Vengeance). The RAM doesn't fail any tests and the computer works like a charm in OSX for days on end, even with heavy Lightroom/Photoshop use.¬†Drivers are up to date.

When my laptop stopped recognizing my external keyboard and mouse I searched the discussions and found an answer that has worked, but only temporarily. It was to do a PRAM reset 3 times and when I do this the keyboard and mouse work fine. But when I disconnect the mouse and keyboard and then later reconnect it will not recognize them. I have repeated the PRAM reset 3 times each time this has happened (4 times) and they work fine but then there is always a problem when I disconnect and reconnect.¬†
After using my MacBook Pro I close the laptop and it goes to sleep. Later when I return to it and open it, sometimes it can't find the network. The computer is able to see that I have an Apple Network available, but it won't connect.Sometimes when I try to connect, it gives me a timeout. How I fix it is to walk over to the router and unplug it and plug it back in. After I get the green light again, I go to the Apple Network and it works.
