Laptops :: MacBook Running Leopard/snow Won't Boot?

Feb 2, 2010

I have a MacBook 13" 2.0 GHz with 1 GB Ram and a 80GB harddrive 2006 model. This machine recognizes all ram, DVD, Hard Drive and ng usb etc. seems to work perfectly. BUT, it will only startup if I HOLD the PowerButton down all the way down until I see the the Apple Logo. If I just hit the powerbutton and go, it will t reboot over and over and over. I have bought new ram, nope. I tried a different HD, nope. I disconnected the DVD, nope. It simply won't boot properly. Once I HOLD down the power button to get it running it works fine, sees the camera, BT, WIFI, clock is at right time, all keys on KB work, and usb peripherials. I cannot reset the pram or vram at all, even while holding the power button down to boot. If I just hit the button and quickly press Command option p r it just reboots like always. Does anyone have any ideas??? I'm at a loss as it works fine once booted. While holding the power button to boot it I see my front led flashing and then hear the several beeps and it starts up just fine.

I have pulled the battery, removed the PSU, held the power button for a whole minute battery or power and let it sit overnight like this but nada, still does this.

I tried to install snow leopard on my 3 mos. old macbook pro and received a failure message with the invalid node structure, rebuilding catalog B-tree message.

Not sure what to do, I tried booting up from the leopard install disk and it took about 15 minutes to boot up and everything is wonky, doesn't work right.

Laptops :: MacBook Pro Drops Connection After Snow Leopard Upgrade?

Sep 3, 2009

o I took the plunge and giddily purchased Mac OS 10.6 aka Snow Leopard the day it was made available. Usually, I have very little worries being an early adopter to new OS releases considering the successful upgrade experiences I've had through the years of being a Mac user.

After upgrading to Snow Leopard from 10.5.8, my MacBook Pro 17" (2.6 GHz, 4GB RAM, 200GB @7200 RPM HDD, non-unibody) would consistently drop it's internet connection whether it was via Ethernet (wired) or through AirPort (wired and wireless are using DHCP). I've applied several supposed fixes suggested everywhere on the Googled web with limited success:* Reset Network settings, deleted "Automatic" settings and created a new setting (called untitled)
* Zap the PRAM (hold Command+Option+P+R on restart)
* Flush the DNS cache(using: dscacheutil -flushcache on the Terminal)

These 'fixes' worked only for a few minutes, and the internet connection would eventually drop again. NOTE: Although other computers and drives were visible on my network, and Instant Messaging via Adium is still functional, which is weird, I could not connect to the internet through a browser, or connect or even to the iTunes store.

Tired and frustrated at this point, I decided to finally call Apple Support (Case #134733179) and was suggested to try the following steps:* Shutdown the MacBook Pro, remove battery, disconnect the power, and then hold the Power Key for 15 seconds. After which I was told to replace the battery, reconnect power and zap PRAM and wait for 2 chimes before letting the keys go.

I was able to get connection for a while but lost it again after a few minutes of usability.And so I called again and was told this time to try:* Trash the SystemConfiguration folder (~/Library/Preferences/SystemConfiguration) and all of it's contents... then reboot.

The above suggestion seemed logical as it would obliterate any existing preferences that may be corrupted and affecting the connection setup. The system would then recreate a fresh preference file free of any lingering old settings. This again worked for a while, but sadly, my wired and wireless connection both drops within a few minutes of usage. It is also worth noting that simply restarting the MacBook Pro regains connectivity as well but drops after a few minutes on both Ethernet and Airport settings.

So today has been an unproductive day considering I spent all my efforts troubleshooting Snow Leopard (10.6) on the MacBook Pro, and couple that with the inability to use several key functionality such as SynergyKM to sync all three machines I have with one keyboard/mouse (not to mention the unpredictable behavior Adobe CS3 has been displaying (especially InDesign losing menus and drawing blank palettes!) and the loss of Letterbox's (plugin) features on and I am now forced to downgrade back to 10.5.8 via Time Machine Restore until Apple resolves or acknowledges this problem (or some knowledgable individual throws this dog a bone and help me out of this misery).In the meantime, I need to get work done and something as fundamental as a stable internet connection should have been high on Apple's "must work" priority list.

Laptops :: Built In Sound Stopped Working After Snow Leopard?

Sep 4, 2009

I have a macbook 2,1, the white one. Has anyone else had their regular built in sound just stop working right after upgrading to snow leopard? I can get sound to play through headphones, but once I up plug them the little sound icon in the menu bar will grey out and I will not be able to get sound to play through the internal speakers.

If I go to the Sys Pref > Sound > Output Pane, it will say "The selected device has no output controls" in the Settings for Selected Device section.

I upgraded my girlfriends laptop to Snow Leopard even though she could care less. Now she's all mad cause the sound doesn't work.

MacBook Pro :: CD / DVD Not Recognized Running Snow Leopard 10.6.8

Dec 4, 2014

Computer info: MacBook Pro 15.4/2.8/2X2GB/500/SD; 2009, running Snow Leopard 10.6.8, MATSHITA DVD-R   UJ-868

I have used CD's and DVD's before on this computer with this OS, without any problems

Now:all CD's show up as untitled, show as having no content, and are listed with burn symbolCommercial DVD worksDVD's made by professional videographers (school event) are ejected

All of the above are readily read and DVD's played, title and content, by my old PowerBook G4, running 10.3.9 

I seldom use CD's or DVD's, so do not know how long this problem has existed, or what may have precipitated the problem.

Hardware :: Put SSD In 2007 MacBook Pro Running Snow Leopard?

I see SanDisk has just shipped it's new SSD product and it is qualified with Mac OS Snow Leopard. If I purchase the SSD is it possible to put it in my 2007 MacBook Pro running Snow Leopard? Would an Apple Store do that for me or would I need to go to a 3rd party vendor?

MacBook Pro :: Das Keyboard Not Recognized Running Snow Leopard 10.6.8

Apr 23, 2012

I've just got the Das Keyboard Ultimate Model S for my 2009 MacBook Pro, running Snow Leopard 10.6.8. I'm using the USB port to connect the keyboard, and the first time I plugged it in, the computer asked me to hit the first key to the right side of the left Shift key, which is pretty standard whenever a new keyboard is plugged into the Mac. It recognized it as a European ISO standard, which it is.

However since then my Mac no longer recognizes it as that kind of keyboard. When I go into the "Show Keyboard Viewer", the keyboard is recognized as a US Standard layout, and an Apple keyboard as well (meaning it doesn't "see" the numpad). You can see it's a US standard keyboard, as the Enter key is horizontal, and the left Shift key is wider.(the rest of the layout is Danish, which shouldn't matter in this case).

How do I tell my Mac that this isn't the correct keyboard? I've resetted the SMC, PRAM and NVRAM. I've tried to find and delete the file "" in my Library -> Preferences folder, but for some reason I don't have that file. I've plugged the keyboard into my iMac, running the same OS, and here the keyboard is recognized correctly, so it's not the keyboard that's faulty.

OS X V10.6 Snow Leopard :: MacBook Running Slow - Restart Taking Over 10 Minutes

May 15, 2012

A few days ago, I found my macbook running slow. The starting time used to be 2+ min but slow down to 10+ min. I tried to reinstal by installation DVD but the time bar showed 5+ hours required. I restarted the macbook and tried to format the HD, after proper steps taken, the time bar showed 17 days. Instead booting from the system, I tried to boot direct from my installation DVD.

After formatted the HD and re-instal the system, the MacBook seems running smooth again. But after installation of other programs, the same problem recurred. The system was getting slow. Re-starting it required waiting over 10 minutes. I tried to re-format the HD and installed the system again but still doesn't work. Under the disk utility "first aid" scanning through the HD, it showed "Invalid key length." and "The volume Macintosh HD could not be verified completely."

MacBook Pro :: Can't Boot From Snow Leopard DVD?

Sep 5, 2010

I need your help diagnosing this early 2007 Macbook Pro running the latest version of Snow Leopard. It isn't mine, rather my sister's, so I don't know the full details of everything as I don't see her all the time. Last December, I swapped in my 160gb 5400RPM SATA drive from my late 2006 MBP into her MBP as I had just bought and installed a 500gb 7200RPM drive into my MBP. I installed a fresh copy of Snow Leopard onto her machine, patched it up, and sent her on her way.

A few weeks ago, she came to me saying she was having trouble booting into OS X and was just having trouble using her laptop in general. The hard drive wasn't making any erratic noises, so I figured the system install had corrupted itself. The problem was I wasn't able to boot to the Snow Leopard DVD. The DVD would show up at boot when holding down the Option key to show boot devices, but when clicked, it would show the Apple logo, then the "prohibitory" symbol and the fans would spin up on full blast, with no further progress.

Booting into Single User mode, I was able to run disk repair and after running it over a few times, I was told the drive was without errors, the laptop booted fine (minus the booting to Snow Leopard DVD) and I gave the MBP back to her.

Fast forward to today, she's having issues booting in to OS X again. It'll show the Apple boot logo, but the small spinning circle will freeze, and the whole laptop will come to a halt. I still can't boot to the DVD either, with the same symptoms as above. I'm sure I can boot into Single User mode, run Disk Repair, and probably be good, but I want to attack this issue at the source.

Is the hard drive I've got in her MBP going bad (I can't hear any of the erratic noises you hear when you know a drive is going bad)? What else could it be? What about the inability to boot to the Snow Leopard DVD? What is the problem and how can I fix it? Thanks, and sorry for the long winded post.

Laptops :: Boot From USB Flashdisk On Macbook?

Feb 16, 2010

I'm going to be testing a 1.83 GHz Macbook with a bad hard drive and optical drive offered for sale. How can I boot from a USB flashdisk? I have a retail version of OS 10.4 on a DVD, but obviously I can't use it on this machine because of the bad DVD drive. I can, however, copy the contents of the DVD to a USB flashdisk using another Mac.

MacBook Pro :: Snow Leopard Boot Times?

Aug 28, 2009

I was planning to get Snowey and a SSD at the same time, but the latter had to wait. So far, I�m seeing at least a ten seconds improvement in boot time with Snow Leopard:

17" Macbook pro unibody 2.93 Ghz, 4 GB ram 7200rpm HD

before SL: boot up from 39 to 55 seconds

after SL: boot up time from 30 to 39 seconds

Ok, so there is no interest in this topic.

For me boot time is a rather important criterium.

And I think the fact that SL reduce this with almost 10 seconds is AMAZING.

OS X :: MacBook Won't Boot After Installing Snow Leopard

Aug 28, 2009

It just hangs at the spinning pinwheel. I shut the machine off and booted it into Verbose-mode (Command-V) and it stops at "Initializing Power Manager" or something very early on. I pulled the battery and unplugged the machine, am letting it cool off (not that there's a point) -- it's one of the original MacBooks that had that "shutoff" problem with the wire that'd melt and short to the heatsink but mine never had the issue because I wasn't using it very often at the time. Any ideas? The drive does show up when I hold down Option.

MacBook :: Cannot Boot After Snow Leopard Installation

Nov 27, 2009

My leopard installation was giving me a lot of headache so I thought of doing a clean install. Now that Snow Leopard had been out for quite sometime and many issues solved; I thought of installing it instead of Leopard. All I did was follow the instructions to install Snow Leopard [the only option with Snow Leopard was that it did an "Archive and Install" kind of thing by default]. It did take a lot of time [1 hour?] and I was finally taken to my desktop. I looked to check if everything was okay. Though there was nothing spectacular about Snow Leopard. I shut the computer down. Today morning I get this and I can't boot.

MacBook Pro :: Won't Boot From Snow Leopard Installer DVD

Jun 23, 2012

I got a used MacBook Pro 2.53 GHz 17" (Mid-2010 - MC024LL/A - MacBookPro6,1 - A1297) running Lion only. 

I want to put Snow Leopard on one of the partitions, because I still need to use Rosetta from time to time.  The computer didn't come with any installer disks... "no problem," I thought, because I own a Snow Leopard installer DVD (which says "Version 10.6" on it). 

But it won't boot from that DVD.   The Apple logo stayed on the screen for seven minutes before I gave up. 

Is that because this computer requires a later version of Snow Leopard? 

What are my options for getting Snow Leopard onto this thing?

OS X :: Is There A Free Way To Run/emulate OS X Snow Leopard While Running Leopard?

Is there a free way to run/emulate OS X Snow Leopard while running Leopard?

I had a billion problems when I upgraded to Snow Leopard but some software that I don't use frequently only works with it so I want to be able to run those apps while still staying in my less buggy OS X Leopard.

I don't want to have dual boot operating systems. OS X Leopard 10.5 is my primary OS.
