MacBook Pro :: Disable Combo Drive Through Open Firmware Console

Aug 27, 2009

I have a mechanical fault with my combo drive (cdrw/dvd) in my Powerbook 12" 1.5 GHz running Leopard which makes it noisy even when there is no disk in there. Is it possible to disable the device by removing it from the device tree in Open Firmware before OS X boots? It sounds like the drive is checking for a disk. I am sure there is not a disk in there as it still accepts and ejects other disks. If it were to be removed from the device tree would this likely solve the problem, or would the power cable to the drive have to be physically disconnected?

I was travelling and added a firmware password a few months back, I now want to disable this to install Ubuntu on a partition of my MacBook - but there are no directions how to in the utility.I looked at the Apple doc I originally used to set the password: [URL]/HT1352, and I cannot find a companion document for taking it off. So, if anyone knows how I go about doing this,

MacBook Pro :: Activity Monitor And Console Won't Open?

Apr 10, 2012

I knew everything was working fine on my Macbook Pro 2.4 GHz i5, 8gb ram, Mac OS X Version 10.7.3. I loaded up my Mac this morning and tried to open Activity Monitor but wont open. When I drag the application to the dock, there is no icon picture for it. I looked on the internet and it told me to load up Console, which I then found done the same thing.

In Utilities I realised the App 'Podcast Capture' was also missing its icon, but since I do not use that, I am not worried.After looking through google again, I ended up using FirstAid and repaired the disk and permissions. That still made no difference.Finally I then decided I could delete the .plist from preferences, to then find neither of the files for Console and Activity Monitor were there? And I had not deleted them.

Once last thing, in Terminal, every time I open it, it comes up with, bash: /usr/libexec/path_helper: Unknown error: -22

Not sure if this relates to it in anyway? The only thing I know that may have effected it was setting up a Minecraft server which I had to use a chmod a+x (file location). Which I thought gave it the commands. Didn't work anyway, but whilst in the middle of doing that I realised all these other issues.

OS X :: Macbook Won't Boot Into Open Firmware?

Sep 8, 2009

So, I'm still having trouble with the MacBook I posted about here. It kernel panics even more frequently now, a month later, about once every 30 minutes. I'm running 10.5.8 now (no Snow Leopard for me!).

Anyway, the problem I'm posting about is that I can't boot into Open Firmware. It works fine just booting straight through to OS X (except about a third of the time I start up it kernel panics right after the Apple logo appears) but it won't boot into Open Firmware. I hold down Command-Option-O-F to no avail and it just won't go. (I'm trying to do reset-all to see if that helps any.)

I tried booting into Open Firmware successfully on my other Mac so it's nothing I'm doing, this MacBook obviously has some serious issues.

I'd rather not have to take this computer to the Apple Store again - every time I do they just reinstall the system/replace the hard drive and don't take me seriously when I say the problem is not with software. (Plus the warranty on this machine is up now and I'm trying to avoid paying hundreds of dollars!)

Anyone know what the issue could be? i really need a new computer hahaha...

Oh! I also tried booting into Open Firmware by holding down the power button continuously as suggested here... the on/off light blinked 3-4 times, the computer made a really long beep (like I was trying to do a firmware update), then started as normally. So I don't think that worked either lol.

MacBook Pro :: Best 2 Drive Combo Setup And OS Strategies

Dec 10, 2009

This is a re-formulated post about using a SSD for boot and apps and a HDD in the optical bay for storage of files. I still want to post it here due to the MacBook Pro specifics surrounding the drives. I am putting in a 160 for the SSD / boot, as it stands right now the drive will have not more than 60GB on it with my music, 13+ GB of mail archive and other files. The rest, movies, websites, photos and any other media will reside on the storage drive in the optical bay. Applications such as iView Media Pro and Mail Steward have safe mount / unmount behavior in terms of operations so those should be fine when the disk is unmounted. I expect to have both drives running most of the time unless is gets rough or I need juice for longer spans. What I am wondering is what strategies for keeping a smooth running combo of twin drives have people been using in terms of keeping as many files off the SDD but not corrupting the OS when reading a disk and then having it unmounted?

I know the "other" thread is a good source but it is 23 pages long at this point but enough people are doing this now that it will be a common question as some point and it is really only touched upon a few times in the other thread. I have used CCC to dupe my current data in 2 locations, so I am safe to muck around with this now. I would expect it to be fine to boot off of any one of the three drives to move the 60GB working set and OS onto the SSD. Should I use one of my external backups to do the initial boot and then re-boot out of the optical to set up the clone to the SSD? It kind of makes sense to me given the fact that the HDD with the native OS will have moved from one SATA location to the other. This just seems different to me than my desktop because this is a mobile device and the way power / drives and other little details interact is worth looking into.

MacBook :: Install An Open Firmware Password On 10.6.8?

May 3, 2012

I tried to download the lastes version of open firmware, but it is incompatible with the version of my computer. Don't tell me to use a disk I got with my computer, that would be for a Macbook Pro, not a Macbook, which is what I have. Please tell me if you can find a link to a firmware password program for Mac OSX 10.6.8, or if you have another way of installing a firmware password.

Software :: Cannot Open JAR File - Error Message In Console

May 23, 2008

I have a Macbook (10.4). When I try to open a .jar file, I got a message like: can't open. In the Console, the error message is: Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

I googled it and it seem that something is missing from my OS, since the .jar file has been "compiled" with something that I don't have (??). Software update is ok, and on the terminal (don't ask me how I arrived there):
java version "1.5.0_13"

MacBook :: Install Snow Leopard With Broken Combo Drive

May 16, 2010

I've been searching but I can't find anywhere where my specific problem is answered. Short version: Does Remote Disc work in Tiger (10.4.11)? Long version: I have the following:

Macbook running 10.4.11; busted DVD drive
PC running Win7 w/ Firewire port
Snow Leopard install disc

I'd like to get Remote Disc running on my laptop and install over the network (using my Win7 PC). I've done the terminal hack which is supposed to enable Remote Disc on MacBooks. However, Remote disc doesn't show up in my finder (not sure that 10.4.11 has a place for it to show). Does Remote disc work with Tiger-Macbooks? Or do you need Leopard? If Remote Disc won't work, can a Win7 PC install Snow Leopard via firewire to a Mac? If possible, I'd like to avoid buying an external DVD drive, as it appears Remote Disc will work in Snow Leopard. Don't have a firewire cable on me but I could buy one -- just want to be sure it will work before I waste the money.

OS X V10.7 Lion :: Console Log Missing From

Mar 17, 2012

In Mac OS 10.6, the had an option to show the "Console Log" which included what looks like the stdout/stderr message of running applications not explicitly sent to syslog. The option showed up as the second option in the system log queries/database queries list on the Log List.In 10.7, the only option is "All Messages" and there does not appear to be a way to view the "console log" as it was in 10.6. Is there a way to turn this on in 10.7? Does the Mac no longer provide a way to see the stdout/stderr messages for running applications (those run as .app and not from terminal)?see attached screen shots (left is 10.6/right is 10.7) with console messages option missing.

PowerPC :: Combo Drive Not Reading

It will draw them in, groan like it's about to spin up, pause, then groan some more. I hear it spin up a tiny bit, but not to the rate it usually does. The fact that it's spinning at all makes me think it's a read head/lens dirty problem.

Mac Mini :: Remove A CD In Combo Drive?

Feb 29, 2012

This is a Mac Mini operating on OS 10.58.  I have a CD in the combo drive, and it apparently has something recorded on it.  I think this CD had started to be burned and I stopped it.  The computer indicates that this CD is not blank.  The result is that it will not eject, even after several attempts using the small eject arrow at the top of the desktop, the use of apple-E, and after repeated efforts with a complete shutdown -- still the disk is stuck in the drive.  I suspect that it's in a loop situation, where it tries to run the CD with not effect, but it also cannot eject it. 

I notice a small black square, appearing to be black plastic, at the far right end of the CD/DVD player slot at the top of the Mac Mini.  In the old days there was such a hole into which one could stick a straight wire, like a heavy duty straightened paper clip, and it would physically eject a stuck disk.  Is there such a thing on this Mac Mini?

PowerPC :: Mac G5 Can't Boot Into Open Firmware

Feb 4, 2010

I have a dual 1.8 PPC G5 power mac that I bought used about a year ago. It came with OS 10.5 preloaded but the only discs I have for it are the original system disks(10.3). I've got it hooked up to a HP 19 LCD via DVI. The other day I tried to boot into open firmware using the command-option-O-F start up command. Well, something happened cause OS X never came up, but nothing else did either. The screen just stayed blank, the fans starting ramping up and just got gradually louder and louder. I tried entering mac-boot via the keyboard thinking that maybe I was in OF even though I couldn't see anything on screen, but nothing changed.

Hardware :: IMac Combo Drive Will Not Read Anything

Feb 19, 2009

I recently began using my computer again after having to replace the power supply. Since then, my computer has refused to read cd's. It doesn't recognize data cd's at all. For audio cd's my computer mounts them but won't play any of the files and iTunes won't play them either. When I try to play audio cd's in iTunes I can hear combo drive doing something. I'm not sure if this is a software or hardware issue.

MacBook Pro :: Firmware Updater Got Stuck - Drive Not Recognized

But after the firmware update failed (updater got stuck), the drive now spins, light on, but the MBP won't see it, and neither will the firmware updater. If so, what was the solution? Just have to go for the warranty?

OS X :: Open Firmware Password - Booting From Another Volume

Nov 5, 2010

I've just set up an Open Firmware Password for the first time. My understanding is that this would prevent booting the Mac from another volume (i.e. an OS X install DVD). After setting up the password and rebooting my machine, I decided to test things out by inserting my OS X install DVD and selecting it from the "Startup Disk" preference pane. Lo and behold, it rebooted from the DVD without asking for the password.

Hardware :: IBook G3 Combo Drive Keeps Rejecting Disks

Aug 17, 2005

I have a " 12Mac iBook G3 (700mhz/128mb/20gb) with combo drive (12.1 16VRAM) Toshiba DVD-ROM SD-R2102. System software installed: OS 10.4.1. I'm a longtime Mac user (have a beige G3 desktop at home and a blue and white G4 desktop at work fairly familiar with OS-X), but by no means a true technie. My brother borrowed it for a couple of months, installed some software he needed to do some work with, then shipped it back to me via UPS. Now, the CD/DVD drive rejects all audio, data or video disks -- the drive whirs for anywhere from about 15 seconds to a couple of minutes, then the tray pops back out. Some disks seem to stay in the drive, but no icon ever appears on my desktop and no interactivity begins with the disk. I've tried inserting disks 30 or 40 times and maybe 3 or 4 have mounted to the point the disk icons appeared onscreen. Of those, a couple were audio and did not start to play music (although in one case, I got iTunes open and the tracks seemed to be registering).

In another case, I got a software CD to mount and tried copying its contents to my desktop , but an hour and a half after it started trying to copy the files, an error message appeared -- sorry, didn't manage to write it down). I have tried booting it up with an old OS 9 installer CD and that seemed to work (although the splash page was the gray apple with spinning gear beneath it -- not what I expected to see from a system 9 cd startup?). A friend told me to try that and if it worked, it might indicate this is a software-related problem rather than hardware, but I don't know. Prior to rejecting disks, the drive seems to whir at a fairly normal volume -- nothing violent or unusual. Sometimes it sounds as if it is working hard and sometimes it is fairly smooth sounding, but as I said, I haven't been able to really DO anything with a disk of any kind since receiving it back from my brother. He says it worked great for him -- before and after he installed some new software -- and that he was using audio, visual and data disks on a regular basis while in his hands.

The computer and all programs seem to work just fine -- except for the combo drive. The only other thing I can add is that he managed to lose two of the remaining rubber feet off the bottom, so now only the battery corner has a rubber foot. Does that slight imbalance make any difference to the reading ability of the drive, by any chance? Any suggestions you can give me to check the cause or cure this problem would be greatly appreciated. My brother is in the dog house with me, yet I do believe him when he says it worked great for him. Also, the shipping container looked fine and he did a good job of bubble-wrapping it. IF it had been dropped by Mr. UPS, could this have caused a problem even if the box looked good? (Shipping was insured, by the way.)

OS X :: Safe Mode And Open Firmware Password Enabled

Nov 11, 2010

I have the Open Firmware Password enabled, which prevents my machine from booting into Safe Mode when I hold the shift key at startup (as expected). As a result, if I want to use Safe Mode I have to boot up from my install DVD, disable the password and then reboot. Very time consuming! I just read about a way to boot into Safe Mode:

(at [URL=""]Apple Support[/URL)]
by entering the following terminal command: sudo nvram boot-args="-x"

I'm a little hesitant to test it out in case I run into some sort of Open Firmware/Safe Mode conflict.
