How to choose 2nd additional SSD as startup disk permanently?

I have installed into the second tray an SSD OWC. I cloned it from the 1TB WD that came with the unit. It works perfectly, but I can't seem to choose it to be the startup disk by default. I choose it and even lock it after choosing it, but when I turn off the unit and start up it starts up with the WD 1TB original HD.
How do I choose this SSD to be the default startup disk. I
Thanks

Two thoughts.
Always when using SSDs have a backup bootable clone (and maybe an image of your 60GB system)
When you zap pram, then drive bay 1 (or SATA port 0) is the 'default' or first in line - that is all.
It doesn't and shouldn't matter which drive bay. In fact the system doesn't use the drive bay ID but rather the GUID identifier, and that it be blessed.
When I erased SSD, Disk Utility first grayed out 8-10% as though 'used' and I then restored small system.
I have no idea why when the Sand Force 2.0 firmware was so important, that OWC took over 3 months, testing? before including it on theirs. But not everyone with Mac has been happy updating firmware on their OWC Mercury (they said they hope to make it easier).
So always have a 2nd bootable drive and image, like external 50GB volume somewhere.

Welcome to Apple Support Communities
Time Machine should be enough to make a backup of your files. Also, it should back up all folders, so open System Preferences > Time Machine > Options, and make sure that there are no folders included in the excluded items list.
If you want to create a bootable clone of your hard drive, you need to use an app like Carbon Copy Cloner or the Disk Utility's Restore feature > http://pondini.org/OSX/DU7.html

Don't buy CleanMyMac or any other dreck that offers to "clean" your Mac for you. Worst software ever.
If there are apps in your Applications folder you don't need any more, drag them to the trash and empty the trash.
In general, it is media files, like music, photos, and especially video that is taking up a lot of space. You can move your iTunes library, iPhoto Library, and iMovie video to an external drive.

Here are some general tips to keep your Mac's hard drive trim and slim as possible
You should never, EVER let a computer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your Mac's Trash icon in the Dock?
If you use iPhoto or Aperture, both have its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you are an iMovie/ Final Cut user, both apps have their own individual Trash location that needs to be emptied, too!
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
To find other large files, download an app called Omni Disk Sweeper.
http://www.omnigroup.com/more
Also, Find Any File
http://apps.tempel.org/FindAnyFile/
Download an app called OnyX for your version of OS X.
http://www.titanium.free.fr/downloadonyx.php
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.

How to install third-party SSD as boot disk in MacPro 5,1

I had so much trouble with this that I thought I'd post a recipe that others could follow.
The first thing you should know is that it's not possible to get a non-Apple SSD recognized in a sled slot of a MacPro 5,1. It just doesn't see them at all, even if (as some suggested) previously partitioned as a GUID partition (which works in a MacBook Pro, but not a MacPro 5,1). This is true even with the most up-to-date EFI firmware. You're going to have to use a PCIe adapter card.
The next thing you should know is that not all PCIe SATA3 SSD adapter cards are bootable on a MacPro 5,1. For instance, even though the Sonnet Tempo SSD is advertised as working for a boot drive in a Mac Pro, it actually works in any Mac Pro *except* the 5,1. In a 5,1 drives on the card do not work as boot drives, either with option boot or if you select it as the startup drive after booting from something else. Also, EFI boot is extended by about a minute -- not the end of the world, but an annoyance. The Tempo card does work well for add-on drives, its very fast. I am pretty sure the Tempo Pro variant of the card also does not work, as the Sonnet support guys told me that they have to use use rEFIt for booting 5,1 MacPros in their lab. I imagine if the Pro worked they would have pointed me at that instead. (Note that rEFIt has been superseded by rEFInd, http://www.rodsbooks.com/refind/. I didn't try using rEFIt or rEFInd because I found a better way, but if you want to dual-boot to Linux those utilities are apparently Da Bomb.)
An Apricorn Velocity x2 Duo card *will* boot, and does not have a long EFI boot delay. That card is a little more expensive than the Tempo SSD (but not the Tempo Pro SSD) but it works properly. It's worth the extra money, especially since it's the only card I could find that explicitly claimed to work as a boot drive on a 5,1 MacPro. And it does.
One caveat: With the Tempo SSD the SSD drives were invisible until repartitioned in GUID format, which also happens if you try to use a third-party SSD inside a Macbook Pro. I found that I could repartition one drive, a Crucial MX500 960GB, using a run-of-the-mill USB SATA2 adapter. Unfortunately this solution did not work with a Samsung Evo 1TB drive, I had to use an external USB3 enclosure. Moreover, the enclosure supported both FireWire and USB3 but FireWire did not work. This FireWire issue might be due to the super-cheap enclosure I was using, so YMMV, but keep in mind that it's possible that you'll need either a USB3 expansion card in the MacPro, or a different Mac, to perform the initial repartition to GUID format.
It's possible that SSDs would be visible on the Velocity card even before repartitioning, I don't know as both of my drives had been repartitioned prior to trying the Velocity. So, it might work ... but you might need to partition externally.
I don't know if pre-partitioning is necessary with the Velocity card, as I only ever tried pre-partitioned drives with it. If you try the Velocity and the drive isn't seen, that's the problem and you'll have to use an external SATA adapter of some sort to repartition before installing on the Velocity card.
After partitioning the drive and installing on the Velocity card, it worked fine. Yosemite installed properly and with reboot it blazed.
Next up, TRIM support. For some reason known only to Apple, the Apple AHCI driver refuses to enable TRIM support for anything other than Apple drives. It's possible that there are or were bugs in some of the early SSDs and Apple is just playing it safe, although I would have preferred to have the option to enable TRIM or not if that's the case. Unfortunately there is no such option, you have to use a substitute AHCI driver.
Unfortunately if you're using Yosemite you cannot use a substitute driver without disabling kext extensions, because Apple will not sign anyone else's driver (at least not at the time of this writing). That's unfortunate, I would prefer to have signed extensions if I could, but realistically speaking you're no worse off in terms of security than you were with Mavericks so it's not the end of the world. With a little luck Apple will either start supporting TRIM on third-party drives or starts signing third-party drivers sometime in the future.
So: Before you can start TRIMming drives, you first need to run this command, or something like it:
sudo nvram boot-args=“kext-dev-mode=1”
I rather like seeing the boot process, rather than just the Apple logo, so I use this:
sudo nvram boot-args=“-v kext-dev-mode=1”
I tried both Trim Enabler (http://www.cindori.org/software/trimenabler/) and Chameleon SSD Optimizer (http://chameleon.alessandroboschini.com/). As of this writing the Chameleon driver is more up-to-date, and comes with some additional utilities that are pretty nice. Take your pick, though, both worked fine in my experiments.
With a TRIM-enabled AHCI driver, kext signing disabled, a Velocity card, and your favorite SSD you are in business.
The only weird thing after all of this is that non-boot SSDs on the Velocity card (or on the Tempo) are ejectable. As far as I can determine there’s no way to mark them as non-ejectable. That’s a minor annoyance compared to the performance you get out of the SSD, though.
Because, with this stuff in there, yowza is the MacPro 5,1 a fast machine. You Will Like It. Enjoy!

This was strange but has to do with how startup disk and nvram interact
http://forums.macrumors.com/showthread.php?t=1795765
I think your problems were solvable and not that the Sonnet card and 5,1 is not bootable, in fact the 5,1 is easier, there are more supported cards.
I have the 1,1 where the Sonnet Pro is recommended but for data only and are not bootable because of the 32-bit EFI firmware. NOT the 4,1 and 5,1. The 2008's are problem child and have a mix of PCIe 1.1 slots, first implementation of EFI64 that also has problems. Also the 4,1 has two PCIe 2.x slots 3 and 4 that share a controller but that simply limits bandwidth.
I would have left the TRIM support and NVRAM changes in Yosemite to a separate thread if you wanted to focus on the Sonnet Tempo Pro support in Mac Pro 2010-12 5,1s.
Also the make of SSD can vary and they also have their own firmware as do bootable controllers along with the EFI of the Mac, all of which have to work together. Meaning it might be that Samsung 840 va 840 EVO vs 840 Pro will all be slightly different but my experience is Samsungs work well (as do others like Crucial with the proper firmware - and there was/is an issue with the firmware of the Samsung 840 but not with booting).
The PCIe card gets seen and treated as external and therefore 'eject' but of course you can't when it is the system boot drive.
One thing I found last week and meant to mention: After installing or changing PCIe cards, RESET SMC made all the difference in the world with the long boot delay. Some PCIe cards will add a few seconds, system has to search the device tree which now shows another controller with multiple devices - and sometimes NVRAM and SMC are what I will call "dirty" and need to be rebuilt and reset.

How do you free space on the startup disk

how do you free space on the startup disk

If your disk is 80% full that is normal. Time Machine uses up to 80% of the disk space for local snapshots. To get rid of these snapshots simply plug in your Time Machine backup drive and run a backup.
If you have less than 20% disk space then it is time to roll up your sleeves and search for what you can delete and what you can offload to another disk.
If you have less than 10 GB you definitely need to delete or offload some files. You may want to maintain at least 20 GB of free space so when your disk starts filling again it will have some room before it hits that 10 GB mark again. More headroom is better. If you let the space fall much below 9 GB you might not be able to boot your machine.
Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
- Empty the trash.
- Start iPhoto, empty its trash and restart the computer.
Deleting files:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second one onto which you will offload some files.
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Moving files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them.
As noted above this will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then  > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

How can I remove files from the startup disk

I am getting a screen when I am trying to quit saying the "MAC OS X startup disk has no more space available for application memory" by closing the windows and removing files from the startup disk will help.
How do I do this?

That error message is misleading. Your problem is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

How to make more space on my startup disk

I keep getting messages that I don't have enought space on my startup disk, I was wondering if I can download

How to fix this error? The startup disk cannot be partitioned or restored to a single partition.

Hey guys,
I am trying to install windows 7 ultimate 64 bit via bootcamp assistant. I open bootcamp assistant from utilities and i get the second window and try to click continue and i get a pop up, saying "The startup disk must be formatted as a single Mac OS Extneded (journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." I looked around on the internet, i found that my internal HD must be set to OS Extended (Journaled). I went into disk utility and i clicked partition tab and the option was set to OS extended (journaled). Any ideas on how to overcome this error so i can install windows 7?

Error is:
1: common
2: misleading and poorly worded
3: space must be:
A: contiguous, that means unfragmented and in ONE section, not multiple
B: files cannot be loced, anchored or in such a manner as to prevent or block partition operation
C: to move, unlock and shuffle files requires booting from another drive or device
Shrink the HFS+ volume by as much or more than you need to set aside to use
If that does not,
Try iDefrag from another hard drive or by burning and using its own CD that is just for consolidating free space
Clone your system (should have backups already, clone is just bootable)
Erase and restore from clone - SuperDuper does consolidate files and free space and result in unfragmented (99% success rate)
None of which has to do iwth what that error message says. This error has been almost a daily threat topic - has gotten less but has not "gone away."

Mavericks requirements > OS X Mavericks: System Requirements
Requires 2GB's or more of memory so you may want to upgrade the RAM (memory).
Mavericks also requires 8GB's of free disk space.
To install Mavericks, you need one of these Macs:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory
8 GB or more of available space\
You can free up disk space by transferring photos, video, documents, etc., to an external drive or burn to CD's or DVD's.

If someone torrents a OS X upgrade on your computer how can you restore it without the startup disk

I recently let my friend use my computer for a few days with the promise that it would run better. When i got it back i found out he torrented Mac OS X 10.7. i have let it sit on my computer for a while but it has caused problems with downloading apps. I would like to know how to downgrade back to the compter was when i orginally bought it. I do not have a startup disk because i bought it from a used mac seller online. also i would like to keep my files, music, games, ETC.

That was an incredibly bad thing your friend did to your computer. A torrent of just about any software you download for the Mac will have malware in it. So that gets installed along with the software you think you're getting for "free".
I wouldn't use that computer for anything where you may type in a password, checking or credit card numbers, or any other type of sensitive data until you've had the chance to backup your important files.
Once you have a way to do so, erase the drive and reinstall the OS, and then reinstall only your legally acquired software.
