OS9/OS8/System 7 :: Can't Install It On IMac G4 17" 800Mhz
Apr 11, 2012
I've just installed Mac OS X Tiger on my iMac G4 17" i know Tiger is outdated, but it's faster than Leopard and Tiger still runs fine.now i tried to install Mac OS 9 too. For some performance reasons. But after the Welcome Screen, the Display turns black and i can't see nothing It's the original Mac OS 9 CD from the iMac G4. And it's the original rom, i never changed anything. Maybe Mac OS 9 doesn't have the right kext for the iMac?

iMac, Mac OS X (10.4.11), iMac G4 17" 800MHz

I know that's below the required speed but there's Leopard Assist. As can be seen on that page, it says "Uncertain" ONLY for my iMac.
Has anyone done it with this iMac? Does anyone know? I'm running Panther now and, these days, that's no place to be. I want to get Leopard on my Mac before I have to <shudder> switch back!

And my second question is, where can I buy Leopard cheaply? It costs about £100-200 on eBay for something that I will need once.

Mac OS X (10.4.11), Apple Imac G4, SuperDrive, 768SDRAM

Just wondering if anyone's tried to run Mac OSX 10.5 on their 800mhz G4 and how the performance is (good/bad)? Obviously the cutoff is 867mhz.

Now, my poor little G4 was just standing there. After a lot of fumbling around, restores, it finally has regained life, running Tiger etc.
Now, I wanted to install Leopard, see for myself what I would prefer, and it would allow to tether wireless internet connection through my iPhone to the G4. But I need Leopard for that, Tiger is too old.
So, after Googling, I found out that if I put my Intel into Target Disk mode, I could use it as external DVD reader, seeing my G4's reader is dead as dead can be.

Further to one of my previous questions i have now managed to get hold of OSX tiger for my Imac G4 800mhz superdrive. However no matter what I try I cannot get this to install. If I go through custom instal it checks my disk and then comes up with a notice saying "mail cannot be intalled on this computer - intallation not possible" or something along these lines. I have also tried restarting while holding down the command button but the 10.4 disk does not appear. I have completely wiped my harddrive and reinstalled my original osx 10.3 and even taken out the airport card and additional ram memory card which i thought was causing the problem.

Does anyone know how the ATI Radeon HD 2400 XT with 128MB compares on performance to the shared 256MB in new Minis? Also, in iMacs with an 800mhz system bus that have 667mhz ram preinstalled, will they take (and run at full capacity) 800mhz ram?

I'm going to be purchasing my 1st Mac within a week or two and I have a question about Mac Pro FB-DIMM Memory placement -- seeing that the Mac Pro comes with 2GB Memory (2x1 GB Sticks) standard and I'm going to be adding an extra 8 GB (4x2GB Sticks) to the system (from OWC for an extra kick seeing that memory prices are very affordable for an extra 8GBs). Would the proper way to insert the 10 GBs of memory be that the each of the 1 GB sticks would go on each riser on Slots A1 and B1 (the first slots on the riser), with the other sets of FB-DIMMs being placed in pairs on each of the two risers? I read the Mac Pro RAM Info at [URL:...] but I just wanted to clarify if I got this correct.

I've bought new memory for my by my Mac Pro 2.8Mhz Quad Core mid 2010. It is 4x Kingston KTA-MP1066QR/8G memory. Installing went well, but it's clocked down to 800Mhz by the Mac. Why? And more important how can I fix it so I will have my 4x8GB @ 1066Mhz?

I have been viewing the forums for the past few months and have finally joined MacRumors as I have purchased an ibook G3 (first mac). I love it to death, it is so portable and even runs like a champ considering it is almost 4 years old. The ibook has a 800MHZ G3 processor along with maxed out ram at 640MB. Anyway I am planing on buying an TV before school starts up again and would like to encode my dvds to h.264. I was wondering if my computer can handle this task. BTW I would need to buy a dvd drive for my computer along with an external HDD. My other option is to buy a friends Powermac G4 with dual 1GHZ processors(he is selling it at $250) it already has a dvd drive and two 200GB HDD so that will save me ~ 150. As I am new to macs and would like to know if the Powermac will significantly make a difference in encoding times or should I just stick with my ibook and save the $100?

I've got a G4 iBook here that is really really slow. It's running Mac OS 10.3.9, has an 800Mhz G4 CPU, and 1.12GB of ram (Built in 128mb + 1GB upgrade).
Activity monitor shows over 800mb of ram free, and about 16000/0 page ins/outs.
The CPU is also about 80% idle.
Something is fishy. There is only 6GB of free hard drive space.. but I don't see how that could cause this nightmarishly slow performance. It takes 5 minutes to open a folder sometimes! Could it be bad ram? Malfunctioning hard drive? Does it sound like a hardware issue or software issue?
I also noticed that there were a few folders in the hard drive such as "Previous Systems" "Rescued files" and "Damaged files." I already trashed "Damaged files" because it was just a bunch of random crap that no one would need and it was taking up space.

I am working on a hardware hack with an iBook G4 800MHz where I can only power the iBook with the AC Adapter--NOT using the battery. When the compy is turned off and turned back on, I am getting this huge error message on the display that my time and date are wrong.
I gather there is no battery on the MB that sustains the internal clock--the compy uses the powerbook battery to keep the clock up to date?
Is there any way to set the system software to bypass or ignore the time and date? This computer is not connected to the internet, and time and date are irrelevant to my application.

My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.

I have an eMac 800mhz and I'm having trouble discerning whether it's an "early" build which needs the original AP card or a later build. What exactly am I looking for in the system profiler to tip me off?

I'm using a iMac PowerPC G5 that I've received from my brother. He gave it to me with a fresh install of Leopard on it, but he unfortunately no longer has the disc that came with the computer that he also used to format it before handing it to me. With that said, I ordered a new internal hard drive. Naturally, I'll need to re-install Leopard, but I don't have an install disc anywhere. How is this going to be possible? Or will it not be? Do I have to buy a new Leopard install disc? If so where and how much?

The internal hard drive on my early 2009 iMac is being replaced but I have to reinstall Snow Leopard myself.I did search in MRoogle and at Apple and cannot seem to find instructions on how to perform a clean Snow Leopard install on an iMac internal HD.
Can I do this? And if so how? Or do you think I should try and install Leopard on the existing Hd in the iMac? I still have these discs but have to get the SL applications install disc out of my drive (it's stuck and the iMac won't boot past the blue screen).

I got tiger install discs for my emac but I cant get it to run the install. I tried putting the disc in and clicking the restart button on the screen that says "Welcome to Mac OS X 10.4 Tiger", but when I click it it just restarts my computer and does nothing. I then tried the alternate install it did the same thing it did nothing but restarted my eMac. I then tried restarting my computer while holding c key nothing once again. Then I tried holding down apple, option, f , and o keys and then typed in cd boot and also tried cdrom boot nether of them worked so i restarted and tried dvd boot/dvdrom boot nothing worked on all the occasion i got a grey screen with a circle with a line through it. What do I need to do to get these install discs to work?

I have a Macbook Pro Intel Core Duo (first generation of MacBook Pro released). I run OSX 10.6.5. My disk utility has detected a problem and says I need the install disks that came with the computer. Called apple and they said I could reboot from snow leopard or the upgrade.** Problem is that I don't have any disks with me except those that came with my brand new iMac. Can I use those to reinstall the system? Is there any other way?
**They also said that after 2007, the install disks that come with computers are keyed to that specific computer so I "might" not be able to use the disk to repair.
Additionally, and I don't know if this makes a difference but I have the airport/time capsule which backs up my computer for easy restore.

I have bought a used Macbook Intel 2.2Ghz 250Gb with 2GB RAM running Snow Leopard. It didn't come with system discs. I have a similar Macbook with a 160Gb HD running 10.5,8 and I have swapped the HDs over. Both machines are running fine. I now wish to reinstall 10.5 on the 160GB HD but when I use my original 10.5.6 system discs it says that OSX cannot be run on this machine.

I've never had these kind of problems with Leopard on my G5, neither on Tiger. Both having installed less than 4 GB of RAM. SL seems to have changed the RAM management quite a bit. I don't know if it's the video memory that is causing SL to slow down the whole system so much that it has to page out each and every newly opened Safari tab or PS document to HDD. Here is a screen shot of the RAM usage: In other words, the page-outs are taking place even despite the supposed FREE Inactive RAM...
