Mountain Lion cannot see fibre raid, Snow Leopard can?

Hi, I have a 3,1 Mac Pro, 8 core, 2.8GHz with an LSI 7404 fibre card. The card is connected directly to my 2 medea raids (no switch). The raids mount perfectly in Snow Leopard, but in Mountain Lion 8.2 only half of each raid can be seen in disc utility. Mountain Lion lists the fibre card as "driver installed" as well. Any help would be greatly appreiciated.

I would expect Disk Utility to still report the Physical drives, even if it could not see the Logical Volumes correctly. Does it see all the Physical drives?
If not, what kind of enclosure are they in? does the manufacturer have anything clever to say about this version of Mac OS X?
EDIT: Have you considered buying and installing Lion and installing it on another drive? It IS still available. You can buy a download code if you call the Online Store. Under US$30.

Mid 2010 Macbook Pro (7,1) - Downgrading from Mountain Lion (10.8.3) to Snow Leopard

Hi everyone!
I am looking for some help with downgrading my macbook pro from ML back down to SL. I'll start off with some information about my case:
I bought this computer mid 2010 - I believe in July, if that matters. It is a Macbook Pro 7,1 model. The computer came with two disks, one being the Snow Leopard 10.6.3 install dvd, and the other being the applications install dvd. I do still have these dvd's, sitting beside me as I type this. Just like many others, I upgraded my computer to Lion, and from there went to Mountain Lion. I have been on Mountain Lion for several months now, currently running 10.8.3. I know a lot of you out there are disappointed with this OS, and many have experienced significant adverse effects on the overall performance of their computer. That being said, I also know that a lot of you have not had these sorts of issues running the OS. As you can tell, I mysef fall into the first category, as I have not had the greatest experience with it. It just seems to tire out my computer at activity levels which, on Snow Leopard, would not be problematic. I say tire out here in that my computer will overheat, slow down, and even sometimes crash (the crashes primarily begin with the spinning rainbow wheel, attempts to quit / force quit the applications I am running, followed by complete and utter frozenness). When this happens, I have no choice but to press the power button until the computer shuts off, then I restart, occasioanlly taking multiple attempts because of kernel panics the first one or two times. Who knows why this happens...I upgraded my RAM a couple months ago from 4GB to 8GB, which has seemed to help some but not fix the problem entirely. So, I have been wanting to downgrade back to Snow Leopard.
Ok so, I have made multiple attempts at this. For starters, I can tell you that the computer simply will not boot from the Install DVD (it is the one which came with the computer, not a retail version or anything like that). Additionaly, I cannot restore the SL DMG file from the dvd, neither to my hard drive nor to a USB drive. Because of this, I ended up trying this: I downloaded the snow leopard installation files (I believe just the content of the DVD ripped from the disc) via a torrent. I then got a 16 GB USB flash drive, wiped and formatted it (Mac OS Extended (Journaled)), and copied to the USB drive the install file I downloaded. I'll also note that I have done the same thing for Mountain Lion, copying the install file from the app store to a separate 16 GB USB drive. Ok, onto the results of my attempts at downgrading:
Each time I have tried to downgrade, I have taken the following step:
1) Power down the computer
2) Insert Snow Leopard USB drive
3) Boot up the computer, holding the option/alt key
4) Selecting the Snow Leopard USB drive
     -It would successfully boot from the USB, and would bring me to the language selection window, as expected
5) After selecting English, the window gives me the option to continue with the install, or access any utilities, and I would go to Disk Utility
6) I selected the internal drive in Disk Utility (the whole drive, not the indented partition), and I went to the partition tab, partitioning the drive to have 1 partition, Mac OS Extended (Journaled), erasing the current partition
     **Note: I have not tried this, but I feel like maybe If I were to first Erase the drive, opting to zero out all data (1 pass) in the security options, then partition the drive the same way as I did in step 6, perhaps the installation would go smoothly without returning any errors...thoughts?
7) After step 6, I would return to the install os x window and begin installation of snow leopard.
     -Every time I have done this, the install has returned an error about mid-way through, and I would be prompted to restart and try installing again
8) Now having a non-booting computer, I would end up powering down, swapping out the snow leopard usb with my mountain lion usb, booting from that, partitioning the drive the same way as before, and reinstalling mountain lion
     -This beings me back to square 1. A working, booting computer on Mountain Lion...
I believe that my issues surrounding the use of my install dvd (that came with the computer) are caused by a bad optical drive. When in mountain lion, if I insert the dvd, it will read it, but it will do so very slowly. For example, after inserting the dvd and the install os x window coming up, if I select optional installs or instructions, each of these folders would open, but take a very long time to display their contents. It also is a struggle to get the disc to eject in this situation.
So, if anyone has had a similar situation and came out on top, I would truly appreciate your help!
Thanks guys,
Nick

I am ready to dump mountain lion and go back to snow leopard

Can someone stop me? I am so frustrated with lion and now mountain lion that I am actually looking at dumping the OS X 10.8 and reverting back to snow leopard.
I have a small office with three mac machines. I have been a fan of the macs for many years, even though we have software for enigineering that requires a windows versions. I have several issues that will not go away on each machine. I have a table below that describes a few of the problems. These problems have left me and my staff with no trust that our work is safe (yes, we do backups and TM). Our work flow is no longer fluid or fun with mountain lion.

Macbook Pro Late 2011, running 10.8.2

Any panic causes multiple versions of Office for mac 2011 autosaved files from one original file., spotlite indexing issues. Sync services still broken in mountain lion. Fresh install of 10.8.2
I am normally a good troubleshooter and have resolved many issues so far. But they just cntiue and I am spending a lot of time resolving problems with the machine's OS that I could be using for productivity. I guess I feel like the old days as an engineer in an office where windows requires a near constant windows administrator.
Is this just me whining? Is anyone else suffering through the OS X 10.7 and 10.8 issues?
Somebady tell me I am crazy... I just want to get back to work.

How to copy and replace new Mountain Lion hard drive with old Snow Leopard drive?

So far I have not found an answer to my question, so I am hoping that this is feasible.
A while ago I purchased a used 2010 Macbook Pro running Snow Leopard that did not have the installer disc. A week ago the hardware died on me, so I replaced it with a new 2012 Macbook Pro running Mountain Lion.
The problem is that I purchased a 1 TB aftermarket HD for my old Macbook Pro and want to replace the current smaller hard drive in my new computer with it. I've already run Time Machine and put all of my data in my new computer so I figured that it would be possible to simply copy that disk image back over to my old drive and replace it. However the computer showed that they weren't compatible. When I tried to put my old hard drive in my new computer there was not a bootable OSX available.
Since Mountain Lion already came on my new computer I do not have an installer that I can use.
Is there anyway I can copy the current Mountain Lion information from my new hard drive and basically have a fully functioning, bootable copy on my old hard drive that I can put back into my new computer?
Thank you.

Well, if you put the HDD from the old Mac into an external enclosure you can use a tool like Carbon Copy Cloner or SuperDuper! to clone the Mountain Lion installation onto the 1TB drive. If you go this route, I would suggest you consider using CCC as it does have the option to clone the Repair Partition as well as the boot volume.
Another route you could take would be to put the 1TB drive into the new MBP, and then boot to the Internet Recover . From there you can re-partition the drive and install Mountain Lion clean on the 1TB drive. During the installation process, you will have the option to use the Migration Assistant to migrate your data & apps. You can use your Time Machine backup for that, or if you have the original drive in an enclosure, you can migrate directly from the external drive. I have used this latter method myself a few times.

Is it possible to uninstall mountain lion and go back to snow leopard

Have an mid-2009 macbook pro and since installing Mountain Lion it has become very slow on startup, shutdown and everything inbetween including random crashes of software. Is is possible to go back to Snow Leopard ?
Thanks

Also you should look at this User tip as well, because your machine is a bit dated and likely needs a new boot drive + more RAM and performance tweaks for maximum Snow Leopard performance.
For Snow Leopard Speed Freaks
Snow Leopard is extremely fast on my Early 2011 machine here, it's because it's a 32 bit operating system that can address up to 16GB of RAM (or more)
OS X Lions are 64 bit operating systems so they act more like trucks and can move better in bulk.
Snow Leopard is like a small race car.

If I have OS X 10.5.8 installed, how do I upgrade to Mountain Lion? Do I need Snow Leopard first?

I have a MacBook Pro from 2008, and I would like to install Mountain Lion, but I currently have 10.5.8 (which I think is Tiger?). Do I need Snow Leopard first in order to get Mountain Lion? Where can I buy Mountain Lion (since I can't get Mac App Store with my current OS...
Thanks!
Jo

You'll need to purchase Snow Leopard (10.6) from the Apple Store before you can use the App Store application.

Why is mountain lion so slow compared to snow leopard?

Just installed Mountain Lion from Snow Leopard (skipped Lion).   I like the features of Mountain Lion but it is incredibly slow in overal start-up and general system responsiveness compared to Snow Leopard.
Running iMac and Macbook Pro and both are the same in really slow performance.

OK, been a busy week but I've installed RAM.
Had iMac 2007 model (iMac7,1) with 2GB of RAM (two 1GB modules).   Upgraded recently to 6GB of RAM (one 2GB and one 4GB module), yes, I know this is above the original specs of 4GB, but this model does indeed support 6GB with Snow Leopard or newer.   This now works fine under Mountain Lion with no spinning multi-colored ball.   With a couple of applications like Safari and Mail open, it has (using Activity Monitor) just under 2GB free memory.   Page Outs are now a very small (close to zero) fraction of Page Ins.   So, it works well.     If you are not upgrading memory then stick to Snow Leopard as it is a much lower memory footprint.
Had Macbook Pro 2008 model (MacBookPro5,1) with 4GB of RAM (two 2GB modules).   This wasn't performing as bad as the iMac with Mountain Lion but was still slow.   Anyway, upgraded to 8GB of RAM (two 4GB modules).   This is also now working fine with no major issues observed.
If running VMWare fusion, then a lot of the memory will be used up.   The free memory is very slim on on an iMac when running VMware Fusion with MS Win XP (ugh!), which I only do for a couple of scientific antenna analysis programs that I like to use that just aren't available on the Mac, but it is workable. Occasional memory address messages appear from the guest OS but othrwise fine.
So, in summary, if you have older machines (with low RAM) or have a multitude of apps open then Mountain Lion requires careful consideration as it needs just over 4GB when a couple of memory hungry apps open. Do anything exciting andmemory usage will increase causing tons of Page Ins compared to Page Outs and you'll be running in slow virtual memory.   So, for machines that you won't upgrade in RAM stick to Snow Leopard.   For modern Macs with 8GB, 16GB or more, then all will work well.
I still wish they could make the memory footprint leaner though.

How do I uninstall mountain lion and go back to snow leopard?

For Snow Leopard Speed Freaks

I have a macbook which is using snow leopard. can i upgrade to mountain lion

can i upgade to mountain lion if i am using snow leopard 10.6.8

As mende1 has mentioned - Mountain Lion will run with 2GB - I've installed it in my niece's 2010 Macbook with 2GB of RAM - let me tell you - it's slow compared to Snow Leopard.
I suggest you upgrade to 4GB of RAM or even 8GB of RAM should you decide to go with Mountain Lion.
Not only will Mountain Lion run better with 4GB of RAM - your apps will run smoother too.
Click on the link below to see how much it will cost you to upgrade to 4GB of RAM or 8GB of RAM, as you can see, it's not an expensive upgrade.
Good luck.

Only use Apple Certified RAM and the right speed for your Macbook so you won't have any issues when you install it.

How do I get my macmini running Mountain Lion to see my Canon USB printer connected to my Airport Extreme? I have a macbook pro running leopard and that works fine. The versions of airport utility are different and I can't even see the printer from new 1

I am having trouble seeing my usb printer from my second gen airport extreme using the newest version of airport utility under Mountain Lion. UGH! And while I can see and network to my Canon IP5000 from my macbook pro running leopard, I can't from my new macmini running Mountain Lion. Any help would be appreciated in configuring my macmini so it can see the Canon IP5000 on the airport extreme. Don't want to "share" the printer from the laptop because that would be a cludge. Thanks ahead

I solved this one based on another post. Turned out I needed the snow leopard IP5000 driver. I had just copied over the leopard driver (I had saved my .dmg file) and installed that but it didn't work. So I downloaded the latest driver which turned out to be for snow leopard and I am guessing since it is 64bit that is why it worked and the leopard driver didn't. Anyway, I also had to hook the printer up via usb to the mac mini to get it to work locally before the O/S would see it over Bonjour via the airport extreme.

You need a "Core 2 Duo" for lion, and I'm guessing you only have a "Core Duo" My wife's macbook is also a "Core Duo" and has Snow Leapord, but cannot install Lion.....

I still have snow leopard, can i switch over to mountain lion or i need to have lion first?

If your system meets the Mountain Lion specs, http://www.apple.com/osx/specs you can go directly to ML from Snow Leopard.

Lion cannot see mountain lion time machine backups

I have just had the HDD on my 2010 iMac changed under the 1TB replacement program. Before wiping my original HDD I made sure my time machine back was up to date. Originally my machine was installed with Mountain Lion, the new HDD has just Lion. I have just tried the recovery utility to restore using time machine and all it can see is my updates before I installed Mountain Lion. Presumably Lion cannot see Mountain Lion backups or something else. Does anybody know how I can simply get my most upto date time machine backup to restore the system.
Thanks

FYI I updated to Mountain Lion and still cannot do a full recovery from any Mountain Lion backups. The backups exist as I can see them in Finder and also when running the Time Machine app. In the app I'm able to restore individual items, but I don't want to waste my life doing this I just want to restore my system.

Mountain Lion cannot see fibre raid, Snow Leopard can?
