On installing Maverick, should external hard drive be disconnected?

When I install maverick! should the external hard drive be disconnected?

You should have a current backup of your system before the upgrade.
Theoretically no you do not need to disconnect,
but I would highly recommend it since you do not want to risk anything going wrong.

When installing to Lion, should external hard drives be disconnected?

I want to install Lion on my iMac. It is currently running version 10.6.8. I have 3 external hard drives connected to the iMac. Should I disconnect them before installing Lion? Thanks...

No need to disconnect any external drives. The Lion installer will let you choose which volume to install to.

Will installing Windows on external hard drive protect mac from viruses better than parallels? Which option is more sound, installing windows on external hard drive or using parallels? My main concern is mac protection. Thanks

Hi,
Thank's for your reply.
Using Parallels and creating a virtual machine, I think it should be possible installing Windows to an external hard drive, shouldn't it?

Install data from external hard drive?

Hi, we have our old macbook data saved on external hard drive (old laptop had water damage but able to retrieve data). I now have new macbook, how do I install data from external hard drive to new macbook? Is it super easy? I didn't want to set up new laptop until I could understand how to install all our old data. Thanks

Do you have the appropriate cable to connect the external drive to to new Macbook?
If you do, the rest is easy. Connect the drive and start up the new Mac. The first steps in the setup will be to enter information about yourself, etc. etc. As you proceed you will be asked if you want to bring in data from another place. Just follow the directions, and the Mac Setup Assistant will do everything for you.
The critical part is making sure the external is corectly connected to the new computer.

Can programs be installed on an external hard drive with my mac pro?

Can programs be installed on an external hard drive. I am running low on space. Final Cut Pro X spins off the rendering files which takes a large chunk of space. Like to at least have those rendered files on an external drive, but can find that option to make it happen.

Hello Ian. I am currently using Lion installed on a WD My Passport 500Gig drive connected to my MBPro via USB, which is still running 10.6.8. Like you I am not prepared to lose all my currently functioning Mac, but also like to see how the new OS runs before making the total switch, maybe when it gets to 10.7.2
So after you download Lion and select to run the installer it will show you which disk to install on, being the default SL drive you downloaded Lion with. But here you can click Other Disk and select the external HD. The installer will run and then boot into the external drive to complete the installation. From then on you can use Startup Disk or the Option key to select the preferred OS.

Can Flash Player be installed on an external hard drive?

I have this game I am trying to install on an external hard drive that requires Flash Player and even though it is installed on my computer the game keeps popping up with Flash Player is required for this install. Would you like to install it now? Is there any way to install Flash Player on my external or get the game's installer to recognize it being on the hard drive. I don't want to install the game to my computer. Thanks for any help.

Flash Player is installed on the Windows system32 and syswo64 folders; it cannot be installed anywhere else.
What does that game require: the ActiveX control, or the plugin? If in doubt, install both.

If possible, will the system run at the *same* speed as the built in hard drive?
ALSO: Am I correct in saying that if I replace my current hard drive with an SSD one?
If so: that *****
Thanks

OS X doesn't matter what disk you boot from, as long as it can be formatted properly in Disk Utility. You can boot from a USB stick drive if it's big enough.
Thunderbolt would be the fastest, the drive would be the limiting factor there. You can find Thunderbolt drives like these at stores like macsales.com. But USB 3 might also feel fast enough.
If you have boot systems installed on many drives connected to your Mac, the way you tell the Mac which one to use is to hold down the Option key at startup. This will present icons of all the connected drives you can boot from, then you just pick one and go.

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

I am having trouble installing. downloaded Mavericks but it will not let me install to hard drive, says that is reserved for Time Machine. I have an external hard drive, but disconnected that before download.

I downloaded Mavericks but can't get past the install; it thinks my hard drive is reserved for Time Machine. I have an external hard drive but dis-connected that before download.
I have Time Machine turned off.

Check to see if you have a file name Backups.backupdb on the disk drive.
If the installer sees such a file it assumes that the disk drive is being used by Time Machine.

Can't install Mavericks to my hard drive: what should I do?

I am using a mid-2010 Macbook with Snow Leopard. I have been trying to install OS X Mavericks, with no real success. When I downloaded and ran the installer, it would not let me select my internal hard drive as start-up disk. I used a flash drive, assuming that, for whatever reason, I would be expected to install in onto my hard drive from the stick; what actually happened (sensibly enough, I suppose) was that, if I left the stick in the USB port when I started up the laptop, I got Mavericks running rather slowly; whereas if I started up without the stick, I got Snow Leopard running normally - and in no instance did I see a way to get Mavericks from the stick to the hard drive. I have found no mention anywhere else of those who install Mavericks having to run it from an external hard drive. What is going on? How do I get Mavericks on my computer? Do I really need, or even want, to?

Hello 123catsank,
It sounds like you are unable to install Mavericks due to this error message that you cannot use the disk to start the computer but it is the only partition you have on the hard drive. I recommend the troubleshooting from the following article. While the title of it mentions Mac OS X Lion, the steps are relevant for Mac OS X Mavericks as well:

How do I install Lion on external hard drive? I have purchased and downloaded through App Store but do not know where the download is located so I can install.

I want to install Lion on an external hard drive. The OS was purchased and downloaded through the App Store but I do not know where the file is.

If you downloaded the installer it will be in your applications folder. Failing that use spotlight start typing Install and it should show up.
This is assuming you downloaded the installer from the app store, and didn't just install it onto your mac. If all you have done is install it on your mac. Go to your purchases Lion should show up. Then click download.
Here is the Support page for installing osx on an external drive.

Hope this helps.

Clean install Mavericks on new hard drive

Hello,
I have a Early 2009 Mac Pro that is currently running Mavericks (10.9.1). There are currently three hard drives in it:
2-1 TB Hitachi HDE721010SLA330 (1 as Boot drive & 1 as secondary storage, both from factory)
1-3 TB Seagate ST3000DM001-1CH16 (being used as a Time Machine Drive)
I want to replace the boot 1 TB drive with a second 3 TB Seagate ST3000DM001. I understand the process for clean installing Mavericks. I know that I'll have to reinstall all my apps and such. Will the cleanly installed Mavericks on the new drive be able to recognize the 2nd 1 TB storage drive as-is? Also, will Time Machine restore my iMovie projects back in place as they are now? And also, not exactly a huge issue if it would arise, but would my VirtualBox VMs be restored to where they are (I know I'll have to re-add them back into VB, that's not a big deal.
I just want to do this as "cleanly" as possible (even though though i know that probably won't be the case, never is with computers).
If I need to provide any more information I would be glad to. Thank you for any help in advance!

Make A Bootable OS X Mavericks USB Install Drive With DiskMaker X
Monday, December 23rd, 2013 | Author: OWC Jarrod and OWC Joseph
Last week, Apple released its Mavericks update with the 10.9.1 version of the operating system – which we hope fixes a few bugs that we saw in the first iteration released Oct. 22.
And if the latest update has you finally looking to upgrade your Mac to the new version of the operating system, it’s worth noting that like its predecessors – beginning with OS X 10.7 – Mavericks is only available for install via download from the Mac App Store.
This means those who previously relied on DVD installs will be unable to do so with this version. Luckily, DiskMaker X helps fill the void by allowing you to make a bootable OS X 10.9 Mavericks USB install drive.
What’s really great about this software is like OS X Mavericks, the DiskMaker X software won’t cost you a thing (however, donations are accepted). All you need is an 8 GB (minimum) USB thumb drive, a USB, FireWire, or Thunderbolt drive or an SD-Card, the OS X 10.9 Mavericks Installer from the App Store, and the DiskMaker X application.
DiskMaker X is fairly straightforward and will guide you through the process of making your install drive. It should be noted that DiskMaker X erases the volume or the drive you chose, according to the options you chose. So don’t forget to backup your data first!

Install Arch on External Hard Drive Bootable on Most Computers

At work I've been using a Mac OS X partition to boot up people's Macs and perform file recovery/partition manipulation. I'm trying to figure out how to install Arch Linux to an external hard drive so that it can be booted by the max number of computers, both PC and Mac. Should I go with grub, grub-efi 32 bit, grub 64, lilo, efistub, etc. for the bootloader? Can anyone give me some guidance on this?
Thanks

With grub, you can actually specify where the config is located. So you can put the grub config for UEFI in the same path as grub.efi, then the bios grub could still be in /boot/grub like usual. Personally, I would use something else though, as I am not the biggest fan of grub.
I think that you need to read through the grub wiki page, as most of the grub knowledge that i have (which isn't much TBH) came from that page. So the fact that I know this crap and I don't use it, means to me that you haven't actually read through that page very closely. It is a wealth of information actually.
I like using the EFISTUB for UEFI, so I am more of a gummiboot or rEFInd kind of user. Then I use syslinux as my backup bios setup.
I know nothing about requiring rEFInd for UEFI booting from an external HDD. I have never actually tried it. But when I set up UEFI on my old macbook in the ESP, the entry just showed up in the mac bootloader. So unless the Macs don't respect some of the basic UEFI standards (which is a very real possibility) there should be the ability to have multiple ESPs.

How to re-install Yosemite without external hard drive?

My rMBP has been having battery issues the last couple of months, and I believe that it's due to my installation of Yosemite. I'd like to do an fresh install of it, but I don't have enough money to buy an external hard drive for Time Machine.
What are some other ways to install Yosemite with just the MBP itself?
Thanks!

Restart with the Command and R keys held down and perform the installation and other functions normally. This process doesn't directly use the external drive, but if a problem occurs and you don't have a backup, you may lose some or all of your data. If you choose to erase the partition with Yosemite on it, you will lose all of the data on that partition.
