HT1338 If I have OS 7.5 installed on an external drive, can I start up from the external drive in that OS when my macbook pro is 10.7?

If I have OS 10.6 installed on an external drive, can I start up from the external drive if I have 10.7 installed on my macbook pro?

Provided that the MBP supports booting from that version of 10.6, and the install was from a retail disk (not a different Mac model), then yes. If it's a newer Pro that came with Lion, it may not boot to 10.6.

I think the DVD player reader on my Mac is going bad. Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive?

I think the DVD player reader on my Mac is going bad. Until I get it fixed Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive? It's ILife 11 if that makes a difference. Finder won't let me see the files to copy. I know - dumb question.
Thanks.

Adding an SSD is not a simple endeavour like adding additional memory or adding another hard drive to a Mac Pro. That's probably why the option is only offered as an option at the time of purchase. Even if your Apple store was willing to install the necessary parts you will probably be paying for 1-2 hours of labor plus the cost of purchasing the necessary service parts (SSD, bracket, cables, etc) which I suspect will make the upgrade cost much higher than what it costs to add the SSD option when purchasing a new system.
I use my system for business and need it to work reliably. Even though I'm fairly handy with tools I would not be willing to risk damaging my system and voiding my warranty by opening my system and removing the logic board and several other parts in order to squeeze in an SSD option and attach the appropriate cables and brackets. I'm also not prepared to deal with the hassles of explaining why my system has unauthorized parts installed in the event I experience issues and need to make use of my Apple warranty. My time is valuable, so I would probably investigate external storage options, or if I needed the speed of an SSD, I would consider selling my existing system and then purchase a new system configured with an SSD.
If you haven't already done so I suggest doing a search on 'iMac SSD installation' to see what's involved. It might help you understand why the SSD option is not offered post purchase.

My 27" aluminum imac no longer recognizes its own hard drive. i start up from the disc, but get no destination to install. whatever am i to do???

it shows up in disc utility as "media" unable for verify or repair. as a target disc all that appears is the install disc. anyone else have this problem??

Boot from your Snow Leopard Installer disc. 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. Is your hard drive at least listed in the DU sidebar? If so, select the topmost entry (drive mfgr.'s name) and not what is displayed for the SMART status in the DU status area. If it does not say "Verified" then the drive itself has died.
I would also suggest you shut down the computer for a full minute then restart doing the above in order to see if the drive "comes to life."

After installing Yosemite beta on external drive, Mavericks doesn't startup from the internal drive

Hi,
After I installed OS X Yosemite Beta on my external hard drive, my Macbook Pro no longer recognises and boots from the Mavericks partition on my internal drive. instead, it starts up the Yosemite installer even when the external drive is not connected.
And when holding the option key during startup, it shows 2 partitions: "OS X Installer" (that I've not created) and "Recovery-10.9.5". However from the system preferences in Yosemite, the partition is shown as a startup disk. and also i can see the Macintosh HD partition and its contents in Yosemite.
Any idea how to make it boot normally when turning on the macbook? any help appreciated!
Thanks!

Try this:
Go to "System preferences"
Click on " Boot-up Disk" (4th row)
Select the disk you want to boot
Restart the computer

Lost most of my music by mistake. how can I retrieve it from the one back up that I have on the computer

I have one backup in my computer but have been unable to retrieve it

Music is not included with the iPhone's backup.

Just started using Firefox; problem re log into New Yahoo; i have typed in my ID including several mistakes and i want to get rid of these from the drop down list that appears when i start to enter my ID. 'Clear History' does not seem to deal with this.

OR even better stop the drop down list appearing altogether;

Can't start up from Install disk

I'm using a MacBook purchased 3/07. System 10.4.11
I can't start up from the Install Disk for Leopard. I only get a screen with the apple logo and the spinning thing. I wait 10 minutes. Nothing happens. I've tried both using the Disk for the start up and clicking on Install icons but when it shuts down to restart....nothing.
Can anyone help me?
Thanks. Lois

Hi Josef,
I left it on for over an hour and nothing happened. Finally called Apple and after an hour and a half of all kinds of testing, restarts, zapping and I don't know what else, the nice man there talked to his supervisor and then had me test the hardware (hold down D when starting). Turns out there is a problem with my ram so now I have to take it to a local technician and if he can't fix it, it'll have to go back to Apple for repairs. Ho hum. I just hope it finally gets working to make all this worthwhile.
Thanks again for your interest and help.

Hi, just updated hubby's iPhone 4 and all of his music has disappeared from the iPhone and from the iTunes library! He does have music still stored on his iPod, but can't get it from the library on his iPod back to phone or itunes. technophobe help pls!

and all of his music has disappeared from the iPhone and from the iTunes library! Luckily he does have music still stored on his iPod, but I can't get it from the library on his iPod back to the phone or to itunes.Please help, but technophobe so put it in simple english please!

Sounds like the music you had on your phone was not the same music on his computer. The iPhone/iPod touch is not designed to be a storage device. When you sync with a computer that doesn't have your music, it deletes your music from your phone.
Was this music you purchased from iTunes? if so, and you are in the US, tap on itunes app, tap updates, tap purchased and tap on the cloud icon to get each song back. If you're not int he us, get iOS5 update later this week and do the same.
But you need to move your itunes library to his computer. Create a user account on his macbook pro for you. From your external drive backup, load your itunes library on it. Then sync as usual! (Don't tell me you don't have a backup for your computer!)

I've backup my iPhoto on WD My Passport. When I try to pull up the photos from the external hard drive onto a different computer, it says "You can't open your current photo library using this version of iPhoto." It says I have to use a later version.

After backing up my photos on a My Passport hard drive I can't open iphoto from the hard drive. It says "You can't open your current photo library using this version of iphoto. You have made changes to your photo library using a newer version of iphoto. Please quit and use the latest version of iphoto." I have done all the upgrades for iphoto. Anyone know what I'm doing wrong?

What versions of iPhoto and OS X are on each computer? You can find out by going to your iPhoto application (from the Applications folder), clicking it once to highlight it, and click cmd-i to open its information window. The version number is in the General tab.
Your version of OS X can be found from the Apple menu, then About This Mac.
The latest version of iPhoto (9.5.1) requires OS X 10.9, so if you have an older version of OS X on that computer, you will have to upgrade to Mavericks and then upgrade to the newer iPhoto.

Hold down the Option key while you boot your Mac. Then, it should show you a selection of devices. Click your flash drive and it will boot from that.

How can I access files from a flash drive that were previously saved using a Windows computer? When I attempt to open the file on MacBook Pro, it is asking to "convert file to"; I also have Microsoft Word installed on the Mac as well.

Format the external drive as FAT32 or ExFAT. Both computers will then be able to read and write to it.

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. But I do not have an install DVD as I got ML as a download from the App Store. What do I do?

I have my new HD in a USB enclosure connected to my MacBook Pro and I want to put a fresh copy of Mountain Lion on it. I'm told that I need to boot from the Installation Disk to start. But I do not have an install DVD as I got ML as a download from the App Store. Can I download ML from the App Store again, but this time directly to my new HD?

Create a data recovery/undelete external boot drive
You can also use Carbon Copy Cloner to clone your present setup to it and boot from it.
Most commonly used backup methods
However, SOME external enclosures are not bootable, you will soon find out.

Ok, since this forum is for Photoshop Standard and Photoshop Extended, we don't know much about Photoshop Elements. There is a Photoshop Elements forum and I'll link it for you since they best know how to field your questions.

Good luck on it!

I have a new MacBook Air with Yosemite (no CD/DVD capacity). I want to install Photoshop Elements 6. Can I do this with the serial number? If pse 6 is not compatible, can I upgrade to pse 7. I do not need pse 12 or 13.

I cannot answer regarding compatibility, but there is no download available for PSE6 if you would need one for this. You might be able to copy the installation files from a disk to some other removable media that the machine accepts. Upgrading to PSE7 would not be possible mainly because Adobe does not sell older versions of their software.
