G5 PRAM reset and boot from CD or HD not working
Here's what I did, in order, and the results:
1) Booted up. Received login screen for Leopard, didn't know the password and wanted to reinstall OSX anyways to sell.
2) Booted to AHT CD that came with machine. AHT loaded successfully.
3) Decided to run AHT (Extended) to test before sold.
4) after 10:59, AHT froze during RAM test. Seemed like normal behavior.
5) 3 hours passed, suspected problem as AHT was still stuck at 10:59 RAM test. Fans Loud. Hard power off using front panel button.
6) had 3.5GB ram installed previously. Removed 2x25MB chips leaving 6x512MB chips installed,
7) booted to AHT CD. Ran Quick test. All passed.
8) attempted to boot to OSX tiger DVD in order to install fresh OSX. Chime but Would not boot.
9) attempted to boot to HD. Will not boot.
10) unplugged machine. Waited >2mins. Tried to boot again. No luck.
11) unplugged and pressed SMU reset button 3 times. Powered on. Chime still, but no boot.
12) pressed opt+PR. Didn't do anything except initial chime. Sometimes mouse LED goes out (plugged into keyboard)
13) pressed opt+OF. Open firmware loads.
14) typed "reset-nvram" ok. Typed "set-defaults" ok. Typed "reset-all" frozen.
15) hard restart. Tried numerous bookings. Would not boot original 10.3 install disk or 10.4 off-the-shelf disc or HD system drive. Will boot AHT disc.
16) will boot to source select when holding option but neither boot to HD or Boot to install disc works, even though source selection screen detects OSX on system drive and Install disc in CD drive.
17) ran AHT quick again. All pass.
Any ideas???
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
See which one your G5 has...

http://eshop.macsales.com/item/Newer%20Technology/BAA36VPRAM/
On the mouse LED going out, any other FW or USB things pligged in? Any PCI cards installed? Tried different USB port for the Mouse?
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Satellite Pro 2100: Booting from a CD-R not working
Hi,
At our company we use the BartPE boot disc to get onto the company network from which we can then use Norton Ghost to image our PCs and laptops. This works really well. However, I've got a Toshiba Satellite Pro 2100 which is refusing to read any boot CDs. It'll TRY to read the discs but simply fails.
I can hear it trying over and over again but it's just not working. I've tried writing using different media and different CD writers, even going down to writing at 8x speed, but nothing helps. Is there a known issue with reading CD-Rs on this range or model?
Tim.Hi
To boot from the CD you can press the C button immediately after notebook starting.
Furthermore it would be very interesting to know if it's also not possible to boot from the Toshiba recovery CD. -
"show my windows and tabs from last time" does not work after upgrade to 8.01
After I upgraded to the latest v8.01 I have lost all my tabbed sites and even when trying to add them and save them with the Tools>Options>General>Start up>when Firefox starts selected feature "show my windows and tabs from last time" it does not hold the saved sites and when browser is restarted it always loses all the tabs and only shows one tab with Firefox home webpage. I need to have several sites open to work and the only way to do that now is to make sure I click the "Use current pages" under General Option in Tools. It is getting very annoying because I keep changing my tabs to different websites during a session and I am used to just closing the browser, relying on having them all back in when restarting Firefox.
Make sure that you do not use Clear Recent History to clear the <i>Browsing History</i> when you close Firefox.
*https://support.mozilla.com/kb/Clear+Recent+History
*https://support.mozilla.com/kb/Firefox+does+not+ask+to+save+tabs+and+windows+on+exit
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

CS3 - Copy and Paste from InDesign to Illustrator NOT working
I am trying to copy and paste some graphical elements from InDesign to Illustrator. The Paste command is active in Illustrator, but when I evoke the command, nothing is pasted. What is wrong?
Apparently it is an issue with Leopard (and Illustrator)
Workarounds:
1) Export from InDesign as eps or PDF, or
2) Copy paste into Photoshop as a Smartobject, and then double click the layer to edit smart object (it will open in Illustrator)
I know, it's a pain.

Drag and drop from Contacts into Numbers not working - any solutions?
I'm trying to get my Contacts into a Numbers spreadsheet. According to the Help files, I should be able to select the Contacts and simply drag them into a Numbers sheet (after deleting the default Table). I've tried this many times over and the drag and drop feature doesn't seem to be working. I can select the contacts and drag them over, but the little contact card remains red when I drag it into Numbers and never turns green to allow me to drop into Numbers. It's the same whether I'm trying to drag one contact or many contacts at the same time. I've also tried exporting a vcard and then dragging that file from my desktop into Numbers, but that doesn't work either. I've tried quitting and reopening both applications, as well as restarting my computer. I'm running OSX 10.8.3 and have installed all new software updates, so I'm just at a loss for what to try next.
Does anyone have any solutions for this problem, or an alternative way to get my Contacts into a Numbers file?
Many thanks in advance!When I tried, it put up a dialog asking me if I wanted to allow Numbers access to my Contacts. Is it possible you tried this and dis-allowed it access?
You might check, anyway. Open Security & Privacy System Prefs, select Privacy tab, and select Contacts from the list of items. Is Numbers listed and is it checked?
Another way to get the contact information into the clipboard is to create an Automator workflow like this:
Open Automator and select Workflow from the options presented.
Drag in the above actions and set the properties as you like. For the Get Contact Information action, you must set the export format to Spreadsheet (tabs).
For the new Text File action, I had to set the Encoding to Unicode (UTF-8) or it would fail.
Select all the contacts you want and then click the Run button in Automator. You can then open the text file with Numbers.
If you envision doing this often, start with an application instead of a Workflow and save it somewhere. Then, you can select your contacts and double-click the Application to export the contacts each time.
The benefit of this method is that you can select all the fields you want to include (at least more than is provided in Drag and Drop). -
How can i install snow leopard on my mac G5 using a command line and booting from an external usb rom, since my disk i have is not a bootable media
Hi.
You simply can't. Snow Leopard is compiled in Intel binary only.
Good Luck. -
I'd like to carry my system, applications and files on a portable Thunderbolt ssd drive and boot from it. I have a Mac Pro in the office, iMac at home, a MacBook Air for when I'm on the road, all with TB. Can a single external TB drive boot all three hardware configurations successfully? I've been told that differences in hardware configurations between the systems make this impossible. Is this correct?
Piece or peace of cake really though.
A quick install on new hard drive or SSD or 10K and less than an hour to move everything over properly.
YOU looked for a quick fix and found none and all the brick walls.
It is not days of work to do a clean install and migrate.
There are few if any apps that need to be freshly installed either though there are updates needed for them to be compliant, any driver or plugin also and that is done ahead of time with research.
And your backup or clone of your system is taken care of - you leave the old system boot drive 'as is' untouched.
Also, better strategy to move most all your home folder (except for its own ~/Library) to ANOTHER disk drive and not on t he system drive at all.
As for applications on its own drive or 3rd party, beeen there done that, even SSD or 15K SCSI - no benefit in performance or organization. -
Can I install Snow Leopard and boot from software RAID 1 (mirror)?
I have a Mac Pro (quad core 2.66 GHz) on order for my office workstation. Yeah, I know new ones are probably coming out early next year but due to budget and upcoming projects I need one now. What I'd like to do is replace the pre-installed 640GB drive with two 1 TB drives and mirror them. The 640GB drive will be redeployed to another machine in the office. Can I boot from the Snow Leopard install DVD, go to Disk Utility, setup a RAID 1 with the two drives, install Snow Leopard to the mirror and then boot off the mirror set?
I've searched and found offhand comments to the effect that installing to and booting from a software mirror is OK, but I'd like to know for sure that it's OK. Any experience that you have with such a configuration would be nice to hear.Yes. But before you do read the following:
RAID Basics
For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:
RAID Tutorial;
RAID Array and Server: Hardware and Service Comparison>.
Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.

Can Leoprrd install on a external USB HD and boot from it.
hi, first post here.
I have serveral external usb hd. I wanted to know if i attach one to my aging G4 1 ghz 512 mb mac.
Put in Leopard Install disc in my dvd drive, will Leopard install on the external and boot from it.
this way I could somehow dual booy 10.4 or 10.5... Is this even possible.
Ps I also have a extrnal firewire drive but would perfer to install and boot from the USB port instead.
I know tiger didn't let me do this....but perhap Leopard will.a Drive Partitioned in GUID will NOT boot to a PPC (G4,G5) machine. you need to Partition the drive using APM. APM will boot on both PPC and intel machines.
A GUID 10.5 startup will be reconized by the system startup prefrerence. but if you try to restart the computer using that startup, it will give you the missing OS icon and then revert back to the system drive.
Also I've noticed that you must be installing from a PPC systme to be able to install on an APM drive. If your on an intel drive, it will force to repartition to GUID before letting you install.
And since PPC doesn't support GUID, you can't install GUID while booted to a PPC. -

I had a repair done on my MacBook Pro and had to have a new hard drive installed. The Apple Auth Repair Shop then updated the OS from 10.6.8 to 10.7.5. Now my iPhoto v 9.2.3 will not open and it sounds like it will not work with this OS. Can you please advise?
You may need many other updates to retain compatibility with Lion. I suggest you reinstall Snow Leopard. Unfortunately, you will need to erase the drive first. Be sure to backup your data if you haven't done so already.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
After the chime press and hold down the "C" key. Release the key when you see
a small spinning gear appear below the dark gray Apple logo.
2. After the installer loads select your language and click on the Continue
button. When the menu bar appears select Disk Utility from the Utilities menu.
After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, click on Options button
and select GUID, click on OK, then set the format type to MacOS Extended
(Journaled, if supported), then click on the Apply button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. After you finish Setup Assistant will complete the installation after which
you will be running a fresh install of OS X. You can now begin the update process
by opening Software Update and installing all recommended updates to bring your
installation current.

i plugged in my ipod and now i get the error message: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" - i have a MAcBook pro and now my USB ports do not work - can anyone help me ???
Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.
Cheers, Tom -
My nano has boxes around its icons, even the around the time. When I tap into my Songs or Now Playing, I can't get out because I can't slide either to the left or to the right. It appeared after I transferred some songs from my iPod to iTunes. I've tried resetting and restoring it but nothing seems to work. HELP.
And the voice over's activated and it tells me to double tap things to select them.
