Intel Mac :: Very Slow, Locking Up And Not Booting Unless Powered Down?
Jun 24, 2012
IMAC very slow, locking up and not booting unless powered down and unplugged. (IMAC OS X 10.6.8 2.5Ghz Intel core) I have performed a detailed HW test twice with no errors and run the disk drive utility with no errors. The computer generally is slow and can spend 3 – 5 minutes with the spinning color wheel between activities. After the computer is fully powered off and plugged it seems to boot normally and work for awhile but then all of the symptoms return. Should I reload the operating system? Today when I booted the machine funny color lines whent across the screen prior to slowly booting.Â
I do have parental controls set which automatically log my daughter off at 930pm when she tried to log in this morning the spinning color wheel ran and ran I could not get the machine to boot by hitting the power button. I need to fully unplug the machine to get it booted. I have also performed all of the software updates. Another strange thing occurred 2 days ago. The machine was locked up and the fan was running at full speed. I had to again power down and unplug it to get it back to life.
I'm a new user to iMac, my kids use it for school and games. Lately it's been locking up and running slow, then takes off to catch up. I'm use to a PC and know how to clear out the registry and some other stuff, but when it come to the mac I'm lost.
I cannot look at any website that has a lot of photos for too long without the mac locking up. I have tried Google chrome with the same results as Safari. I looked on the forums and saw a flush cache command through terminal and tried that with no luck. I don't know if there is anything like the windows task manager to just kill the one app without rebooting.
I'm trying to put a password on a few pages documents using the 10.5.8 operating system. I realize it's sort of out of date, so that could be the problem. But i've been watching some videos that say to click on inspector, then the blank page, and then check the box that says 'require a password.' Only thing is that I don't see that box to check at the bottom of inspector. Â
i've got an optibay installed in my uMBP for about 3 months now. In the optibay I have a 60 GB SSD, from which i boot. My other harddrive contains my OS X home folder & a bootcamp partition. I really love my setup, it's perfect for my, until I saw a buddy in my class boot his MBP: after he pressed the button, it took about 2 sec to show the apple logo. He doesn't have a SSD, and the exact same machine, and yet me manages to boot faster then me. (We also both have 10.6). I searched about this problem, and the only thing i could find was to make sure that your OS X partition is set as boot drive. Here is a screenshot of my boot drive menu: I found it strange that my bootcamp doesn't show up there. I always boot in bootcamp holding the alt key, not using this preference pane. Here is a video of my macbook booting: [URL] I found this ting called rEFIt?
It seems that my MB(unibody 2.0Ghz) has some problem. I recently reinstalled leopard (and some softwares). It takes a little bit more than 2 minutes to boot. Worse comes with Windows 7 beta. I tried both 32bit and 64bit versions. It takes more than 5 minutes to boot! I saw some guy showing some comparison of boot time on youtube. It seems that Leopard should take < 1 minute and Windows 7 takes < 2 minutes (with the same hardware!). My MB takes around 3 times more than other MBs. Where should I start? I recently ran memtest and it turns out to be okay. HDD S.M.A.R.T also reports 'verified'. I'm not sure what would be the next.
I've recently upgraded my MacBook Pro into MAC OS X 10.6.2 and I started to experience a low booting time (over 17 seconds). Another issue, when I start the computer I always get the starting screen where the apple logo is shown as zoomed. I tried to check the display but its fine.
i just bought a new uMBP 15 2.53 last night and i bought a Seagate 500GB 5400rpm HDD to replace the one on board. I installed the HDD and SnowLeopard install went through great but after install every time i boot up, it takes a long time on spinning gear. It eventually loads up but takes a while, I ran Repair Disk Permission and Verify disk and everything turns out fine. I even ran Apple hardware test on HDD and tests passes. I haven't installed 1.7 EFI Firmware since i've read that it doesn't work so well with third party HDD or doesn't work at all.
My MBP (about 2 years old, Santa Rosa) is having some major issues both starting up and going into sleep. First off, I'm using 10.5.8, everything's updated, I don't have a bunch of stuff on the startup processes (quicksilver and iTunes helper) and I'm plugged into a power source. When I start my computer (since yesterday) it has been taking an abnormally long time at the grey screen before the Apple, the grey screen with the apple and the rotating wheel, and then it goes to a light blue screen for 5 or so minutes (repeat: minutes) until flashing light and dark blue and finally taking me to the login. Not only that, but my computer will not go to sleep when I close the lid. Instead, the screen turns off and the hard drive and fans keep chugging. What's more annoying is when I then try to open the lid to manually turn it to sleep, the screen won't turn on. This usually requires a hard reset, which then takes 10 minutes to start up.
I just got a brand new macbook pro 13". I'ts booting in about 3 minutes without power. and then takes about 3 minutes after I log in just to get all it's s***t sorted out. I ran that 32/64 bit kernel application and put it back on 32 bit after it booted slow in 64 bit. Otherwise I dunno. Is this this supposed to be so slow?
After updating to Mavericks my MacBook Pro drains the battery quicker and is also booting from empty battery in sleep mode very slowly. It also gives the feeling that it has slow down a little.
Problem description: MacBook Pro 2011 gen. has become slower after Maverick update. The battery also drains quicker. It takes much longer to boot, specially from empty battery in sleep mode.Â

On my mid 2007 Aluminum 24" Intel Imac shows nothing but a white screen when powered on even though according to the diagnostic LED lights which are all powered on and green the logic board, video card, and everything else are speaking back and forth to each other perfectly fine. Does this mean the LED screen is bad or (from what I've read) is it a possibility the hard drive is bad? I know the optical drive is bad and will not spit out any discs. The #1 reinstallation disc for the OS is stuck inside right now. Before I order a new screen, inverter, and optical drive I figured I should ask in here to see if it is just bad hard drive or something else. Wouldn't the LED diagnostic lights tell me if the hard drive was bad?
recently my Mac is really slow, slow on startup(took around 1-2hours), and slow on task(more than 5 minutes delayed time on every single task), I don't know what happened to it,
My Mac specs: Â
1.Mid-2010 27 inch iMac,
2.Original 4g Ram upgraded to 12g
3.1TB HD has got more than 400gb free space.
4.i3 processor
5.Using latest Lion(I think it's 10.7.3)Â
Problems: Â
1.Startup tooooooooo slow, take more than 1 hour
2.Extreamly slow on tasks. Without any apps opened, every single click, it turned into the 'colorful fan', for instance, open finder, it took more than five mins, and it's not only the finder, it's EVERYTHING!!!!Â
What I have done so far:Â
1.I have reduced the login items
2.I have changed the password login to the automatic login
3.I have tried verify disk permission, verify disk, repair disk permission and repair disk
4.Unplug all unnecessary items(monitor, external drive etc.)
5.Run couple of time of 'clean my Mac', get rid of all the trash.
6.Cleaned the cacheÂ
Due to the ridiculous, frustrating startup, that's all I could do, however, none of them worked.
Now I am using recovery HD to reinstall Lion from a disc, but I don't know if it'll work or not.Â
I don't have another Mac, I don't have backups(don't want to lose my data),that's my situation.
Info: iMac 27'', Mac OS X (10.7), iPhone 3GS,iPad 3G/Wifi 64G, Sony vaio CR
My Intel MacBook is in the shop, and I swapped out my hard drive before I sent it in and put it in a USB enclosure. I was able to boot my friend's MacBook Pro from the drive, but my G4 Mac Mini is not seeing it as an option (upon startup or otherwise). I can read files from it, but I really need to boot from the drive for some other things (cookies, passwords, and especially the ability to sync my iPod touch).
I have changed the Everyone permissions to "no access" in MacintoshHD, when I restarted I can see only the white screen. The OS is not booting. I tried using the Disk Utility from the DVD, but no changes, it is still the same.
I'm trying to boot a relatively new intel iMac. I can boot to a blue screen, in which all that happens is the music that happens with the welcome video of mac OS X. Â
I currently have no keyboard to do diagnostics with because I don't have the wireless keyboard that came with the mac, nor a wired keyboard. I'm planning on borrowing a simple wired keyboard to use to diagnose the mac in verbose mode and safe mode etc.Â
The owner of the mac has done a complete reinstall, hence the welcome video music, and that hasn't worked, as the screen shows no sign of anything other than blue.
I Upgrades to Lion last year. Two months ago, suddenly the screen of the iMac went black. I tried to boot but it didn´t. After waiting one day, it worked and i made a backup and I installed Lion again but this time not updating.It worked, never happened again till yesterday. The screen went black, I still could listen to the song that was playing on iTunes but after a while it crashed at all.Hours later could start the computer doing everything i read here: SMC, PRAM reset, start with D, with shift.... and i made the backup but when i was going to install Lion again it went black again and I couldn´t restart my iMac.I´m afraid it´s the NVIDIA card, but i can´t be withouth the computer some weeks. Is there anything i can do to fix it or to boot at least?
When I turned on my 13 inch Macbook this morning I got a black screen with the message "No bootable disk, insert startup disk and press any key". This has never happened to me before and I am wondering what the cause is and how to avoid it in the future. I got the system to start by pressing and holding down the option key.
a bit complicated.  I have a 3 year old iMac, Snow Leopard 10.5.2 on the dics, but I updated it so..a pretty receent version of Snow Leopard. I had had kernel panics before- it turned out to be a bad RAM chip, replaced it and it fixed the problem.Â
This time, I was hoping it was the same. I got a new RAM chip, swapped them out and ID'ed the bad one. Reseated the RAM. Probelm is, when I was trying to fix the problem, I had booted in Safe Mode. Now the iMac starts up normally- the chime, the Apple- AND the Safe Mode bar.
Which progresses for about 5 seconds before another Kernel panic descends. This happens whether the keyboard is connected or not. At this point the Safe Mode at startup bugs me more than the kernel panics! Sigh.Â
I wonder if there's any key combo on startup I could try to at least get out of Safe Mode before Kernel panic sets in. When my laptop has a kernel panic i can usually repair with Disk repair on CD.  I realize this sounds hopeless! And i need it repaired, but money is an issue.
I have a problem with my iMac. I have on a second partition lion installed. Everything worked great, but since I updated to 10.7.4 booting needs about 5 minutes. Already checked the partition and the access rights.
I just replaced my HDD with the new intel 160GB SSD. Everything is amazingly fast except for the booting process.
After I shut down the computer(which is extremely fast, about 3 seconds), I start my MBP, yet what's been puzzling me is that the time between pressing the button and appearing of the Apple logo last at least 15 seconds, after that, everything is just normal (fast, fast!!).

hey my friend is having a problem with his imac when he turns it on he gets a grey screen and stops there. there is also a grinding noise near the back maybe the hd or disc drive? it grinds 10 times then stops then continues for a couple minutes and then he gets a question mark on the screen.
My 24 inch iMac is not getting pass the apple logo. It acts like it's loading, but then the little progress spinner (not sure of the name) stops spinning after 2-3 minutes. It never wants to get pass that. I'm running the latest version of Lion.
Here's the specs: 3.06GHZ 4GB 500GB NVIDIA GeForce 8800 GS
So far I've tried using disc utility on my snow leopard disc....it doesn't load. I've tried to start in safe mode...it loads about half way and stops. Oddly enough windows xp works in bootcamp. It runs okay besides when I try to move windows. I'm guessing it's the graphics card. No idea really. Here is a video I made to show you what I mean: [URL]. I've also tried installing a new 1TB HD and it still won't boot from a disc for some reason. I tried install snow leopard through the internal superdrive and with an external superdrive. No dice.
I want to write a few CD's containing images but I dont want the people been able to copy or drag the images from the CD's onto their Hard Drives etc...
