Os X Leopard Dmg Install
Waltruda Monie
It sounds like you don't have the original install DVDs that came with the MBP (MacBook Pro). If you have an external DVD drive available to you then I would suggest running the Apple Hardware Test version 3A171 that came on the original install discs with that model.
Also you need a retail version of Snow Leopard (barring the original install discs), if you have the packaging, then you could see if it has the green dot that says 10.6.3 on the front of the box. You cannot use the original release of the retail Snow Leopard install DVD as your computer probably does not support even a minor version of the OS older than it shipped with (which was 10.6.3). If you're not sure, when you boot up from the install USB check on the "About This Mac..." menu item under the apple, or put in the machine you used to clone the drive and navigate to it and look at the read me files.
Also, note that a DVD that came with another computer, unless it's the same model as yours, will not work to install. So, if you took the install DVD from even the first release cycle of a Mid 2010 Mac Mini that had 10.6.3 on it, it still will not install on your machine.
Just this week I opened up a machine and it a) had a bad Hard Disk Drive, b) had a dirty/faulty Optical Disc Drive (aka Superdrive, dvd/cd drive, etc.) and that was possibly ejecting discs from a stuck trackpad clicker c) would not boot up from a USB Installer of OS X Lion until I removed the faulty Hard Disk Drive!
You might also have a bad, corrupted USB drive, I would use whatever other machine is at your disposal and run verify disk on the USB drive as well. If none of the other things seem to work then I would even erase and Reformat the USB drive as HFS+, then clone the Snow Leopard install DVD back onto it.
If this is a backup copy of the Snow Leopard DVD there is a much greater chance of something going wrong with DVD. If memory serves correct, you actually need a DVD-R DL, known as a "Dual Layer" disc to make a backup copy of Snow Leopard. It can't be a DVD+R DL (notice the "+" symbol") known as a "Double Layer" disc. I wouldn't burn it at higher than 4x, and use a known good burner, maybe run a laser lens cleaner on it first if possible.
Note: If you're still having trouble after checking these things out, please let us know what tools you have at your disposal to continue working on this, for example, another computer, an external disc drive, a bare drive dock, tools/ability/confidence to open up the machine and work inside, etc.)
I just bought a new 1TB Seagate Sata Solid State and properly installed it into my 2006 model Macbook because I was running out of space. But I can't figure out how to get snow leopard back on. I've been researching all day and I've tried partitioning the Snow Leopard installation disc and it wouldn't let and I've also tried using my 500gb external hard drive with the time machine back up but that also won't work. I'm not sure what to do and when I go to disc utility it picks up my new hard drive, so I'm pretty sure it's compatible.
And also, I've seen people talk about the "GUID" and in the disc utility when I click on my external hard drive it says "Partition Map Scheme: GUID Partition Table" what exactly will that do? I'm trying to get all of my files from my external hard drive onto the new hard drive. I also have the snow leopard operating system on the external hard drive
If you still have the original internal HDD with the OSX and your data on it, install it into an enclosure, connect it to your MBP and boot the MBP holding down the OPTION key. It should display the external and the internal HDDs. Select the external HDD.
When the MBP boots, select Disk Utility and opt for Disk Utility>Restore. In the 'Source' field drag the external HDD and in the 'Destination' field drag the internal HDD (from the left hand column). Click on Restore. All of the data on the externall HDD data will be copied to the new internal drive, including the OSX. Then you will have an operable Mac.
The advantage of cloning is that it copies all of your data from the original HDD to the new one in one step. In order to do that, you have to place the the new drive or the original internal drive in an enclosure to make the clone.
If you cannot do that, then you will have to format and install an OSX on the new Seagate SSHD that you have placed on your Macbook. Since you indicate that you have Snow Leopard, you will have to use that disk for the installation.
Yes, you can use an external drive (one purchased with a HDD already in an enclosure) but you have to copy the data from the Macbook to the external drive with the original HDD still in the Macbook. Then you can insert the new SSHD in the Macbook, install the OSX, and then transfer your user data from the external drive
The other option is to install your original HDD into the Macbook and then clone it to the external drive. Install the new SSHD in the Macbook and then clone from the external drive to the Macbook SSHD. This is a two stem process eliminating a new enclosure.
Alright, since I have already copied my whole system and all of my data onto my external I'm gonna try to just install snow leopard onto the new hard drive using the disc and then try from there. If that doesn't work I'll go buy an enclosure. I'll let you know how it goes, thanks again!
In testing on my test MBP, it hung up after the restart, but I have different equipment than you have so I hope you will not experience the same issue. If you do, let me know and we will try other options.
If the answer to the first question is YES and the second is NO, Install the old hard drive in the enclosure and connect it to the MBP. Start the MBP holding the OPTION key. The display should show icons for the the external and internal hard drives. Select the external hard drive. This should start the MBP.
I also tried putting the old hard drive in the enclosure and I got it to run but it's running off of the old one and not the new hard drive that is currently installed in the macbook. So I tried switching the start disc to the new one and it just wouldn't even show up as an option. So I downloaded a copy of snow leopard of the internet and tried installing it on to the new one but it said it could not be installed on the new hard drive and that an error occured while evaluating Javascript for the package. I don't understand why none of these attempts are working. I have the gray disc for snow leopard by the way.
My Mac currently is running Snow Leopard (10.6.8), and I would like to develop with Java 7. I downloaded the Java 7 OS X installer from Oracle's website, started to run it. Unfortunately, I was immediately greeted with a message that said the installer is supported only on OS X Lion (10.7.3). Is there any way I can get Java 7 on my machine with Snow Leopard? I am not buying a new OS just to upgrade my Java. I googled around some, but I am not finding much. I'm hoping I can find some help here. Thanks.
What you want is not impossible but for sure NOT recommended but... once you are sure that this is what you want, here is an easy way to install Java (or any software for OS related matters): - navigate to you MainHD/System/Library/CoreServices/SystemVersion.plist - backup this file !! - open it in Text editor and alter the product version:
Boot from the Mac OS X Snow Leopard Install DVD, and from the "Utilities" menu, choose "Disk utility". From there you can reformat your hard disk. After doing so, quit Disk Utility and you can perform a clean install.
It occurred to me after posting this that, while your question clearly states you want to format your disk, I wanted to mention that this will erase all data on your disk, including applications and your data. So make a backup first. Alternatively, you could just perform an "Archive and Install" which will give you a clean OS, but leave your data and applications in tact.
The same laptop boots from its own hard disk fine so I'm pretty sure the RAM is OK. And the same DVD can be booted on other laptops. It is a generic Snow Leopard 10.6.3 installation disk, not a machine-specific one that came with some other hardware. Also on the MBP that can't boot from that DVD I can actually read the disk fine as media in the optical drive so I think that drive is OK.
I think I can get around the problem by using another Snow Leopard machine erase the disk on the laptop booted in target mode and then reinstalling to it from the install disk mounted as media on the second Snow Leopard machine but I just wondered why I was getting the three beeps. I hope I don't need to revert my firmware somehow.
What version is your MBP? If it is a early or late 2011 (or even a late 2010) and you are trying to use the Retail 10.6.3 DVD that may be the problem. That DVD may not have the correct drivers for your system. I know this is true IF it is a early or late 2011 model. You need a machine specific disc or a disc that has 10.6.8.
I'm seeing something very similar here, with a MacBook Pro 8,1. I've run Memtest over the RAM several times, and it passes with flying colours. The computer consistently boots fine from its internal HD and from external volumes over Firewire.
Trying to boot from a TechTool Pro DVD, however, is giving me the three beep error every time. If I boot up holding the option key, I get the screen showing the available boot volumes, and this works fine until I select the TTP DVD. Once I try to boot from it, the computer starts beeping then freezes. I know the DVD is fine, as it works fine booting other Macs of the same vintage.
Well after I installed Snow Leopard to the MBP again (from an iMac which was seeing the MBP as a target disk) now it will no longer boot from its own hard disk but gets the perpetual three beeps. When I started it would boot from the hard disk but not from the DVD.
