what software have you developed? id love to look it up!
well last time i spoke of it here on tpu the thread got deleted because it violates apples EULA.
remember what i did with all those sr2's i built and sold?
oh, i see. i wasnt sure if you were talking about actual programs i could use for apple rather than hacks.
not hacks at all.
just kexts, and bootloaders.
i have done a few small things on actual mac's but nothing worth mentioning.
im still learning with hopes to become someone, someday.
They can handle it, but not nearly as well as Tiger.
Got a problem. I bought some 8.5GB DVD+R's today so I could put 10.5 on one to install (It's bigger than a 4.7GB DVD). Turns out I can't get the G5 to recognize 8.5GB DVD's. I've tried the one I burnt 10.5 to and a blank one, it just acts like it's trying to read it for about 30s before spitting it out. The G5 reads 4.7GB DVD's just fine and I haven't had any problems with the drive before. What could it be?
Is it possible that it's one of the older Superdrives that doesn't have Dual Layer support?. You can use System Profiler to check. Apple has used standard Pioneer internal drives as their "SuperDrives" for years. You can get the newest one for like $30 at Newegg.
Pioneer CD/DVD Burner 24X DVD+R 12X DVD+R DL 24X D...
Well you're right about one part, it doesn't support DL burning. But even if it doesn't support burning DL's it should still read them right? I've tried other media and the problem seems to be just with DVD9's (DL DVD's) and nothing else. It won't read them, just spits them out after gargling it for some seconds.
I opened it up to see if I could ghetto rig an extra lappy DVD burner to it to test and there was just no way, the power/data connection was impossibly placed.
Also, it's an AIO iMac so that standard SATA DVD burner there couldn't fit.
i got a 512mb ddr1 stick you can haz for free
its the one you need, was in a old mac mini g4 i fixed for a customer yesterday
Nah I've got all the memory I need man, the problem now is with that drive. Something's up
I had to burn my 10.5 disc @ 1x on a PC using UltraISO. My g4 Powerbook would read it then. Funny thing is it has the DL super drive and can read dvd's it burned at up to 8x just fine, but i had no choice but to burn the 10.5 disc and iLife 08 @ 1x & 2x respectivly for them to be read on my mac.
Yeah it doesn't support dual layer. Too old. Run into this all the time at work.
So then my only other option for upgrading to 10.5 would be to go through the long, drawn-out process of converting the 10.5 .iso to a .dmg?
Uh well a commercial 10.5 disc would work fine. Why are you having to use a burned one? Perhaps this info is in the thread, sorry...
Hm I found one on eBay for $10 shipped. How does Apple fit 10.5 onto a single non-DL DVD? They must be wizards.
Yeah good question--and to be honest I just always assumed these older drives couldn't read DL but maybe there is something else going on here. This thread looks like it could be of help:
Ah, haha forgot about that! I was really just saying that the drive might be faulty. It's possible that the iMac just uses a generic Matsushita/Pioneer/etc optical drive typically used in a laptop or similar device.
In addition, I was being a dumbass and didn't clearly read what you wrote the first time around. I though you were saying that you were having problems burning dual layer discs, duh!
Really I'm about tired enough of messing with it now to be content with 10.4. It just grinds my gears that I bought some horribly overpriced DL DVD's and it won't read them.
Well, the retail disc is a DL disc, as its a universal disc meaning it has both PPC & intel libraries on it. I really doubt the iMac drive cant read DL disc, i'm thinking its more an issue with them being "burned" more than anything. Thats why on my mac i had to burn the disc's so slowly; to try and make the pits more distinguished and reflective. i do not see how converting the ISO to DMG will help. Have you tried using an external dvd drive or maybe a usb to ide/sata converter?
The thing is, I burned it as the lowest setting. Also and most importantly, I've tried completely blank fresh-out-the-box DL DVD's in there and it would not read them, just spit them out. But, as I understand DVD movies are on DL DVD's and it does actually play DVD movies. Something's just not right.
Download Applejack also. Great program to maintain that OS. That and Onyx.
I wonder if it's possible if maybe the lens is dirty? I have a drive that I know I need to hit with compressed air when it has trouble recognizing discs and it ejects them. I just stick the sprayer straw thing in there and sure enough, it recognizes discs when they are inserted again.
No. A dmg is just a compressed iso. When you burn it, it decompresses, defeating the purpose.
Just grab the CD install version.
Did you burn OS X on a PC? That hardly ever works properly. If you didn't, you may just have shitty DL discs.
Again, just grab the CD version if possible.
You can also use an external Firewire drive if you want. In Disc Utility, use the restore option. Use the iso as the source, and the firewire drive as the destination. After it's done copying, restart the mac and hold down the Option key. That will let you select any bootable volumes that show up.
Well I don't have any firewire drives and I don't want to go about buying a CD version secondhand. I guess it will be keeping 10.4. No hits at all on CL yet, I'm going to have to drop it to $200 to even get bites I think.
eBay it. You'll get more hits.
And who said anything about buying? You already own a legit copy, borrow(cough) somebody else's CD version.
