How to choose boot volume under Yosemite

I just installed Yosemite on a partition of my internal HD. I expected to be able to boot back into mavericks by holding the Option key down when restarting. That doesn't work. How can i start up again using my Mavericks partition from before?

Thanks very much. It's been a long time since I had alternative systems, and I had completely forgotten that Pref.

How to disable boot chime in Yosemite?

Hi everyone,
I'm trying to disable the boot chime in Yosemite. Previously I was able to do this by way of a terminal command (sudo nvram SystemAudioVolume=%80) but this doesn't seem to work in Yosemite.
I know why the boot chime is useful and why I should just mute my speakers before shutting down, but I just want it disabled once and for all.
Besides the use of 3rd party apps, is there any way to disable it?
Thanks for any input.

This worked in Mavericks 10.9.5.
I had this scrapped from someone else's post.
Basically what it does is when you log off, it mutes the volume. On log-on, it un-mutes so your normal volume returns.
-Create scriptfile for muting:
sudo nano /opt/local/bin/mute-on.sh
#!/bin/bash
osascript -e 'set volume with output muted'
-Create scriptfile for unmuting
sudo nano /opt/local/bin/mute-off.sh
#!/bin/bash
osascript -e ‘set volume without output muted’
-Make both files executable:
sudo chmod +x /opt/local/bin/mute-*
-Check if any hooks already exist (these will be overwritten, so make sure it is OK for you)
sudo defaults read com.apple.loginwindow LoginHook
sudo defaults read com.apple.loginwindow LogoutHook
-Add hooks for muting
sudo defaults write com.apple.loginwindow LogoutHook /opt/local/bin/mute-on.sh
sudo defaults write com.apple.loginwindow LoginHook /opt/local/bin/mute-off.sh
–to delete the hooks, use the following:
sudo defaults delete com.apple.loginwindow LoginHook
sudo defaults delete com.apple.loginwindow LogoutHook
-Note that script files must be owned by root.
I wish Apple starts rethinking these unneeded clutters that really annoys new mac users.

How to open .caj file under Yosemite system?

Caj viewer is for opening documents from Chinese Academic Journals. After updating my system to Yosemite, Cajviewer software is no long be able to installed. which means I cannot read any Chinese Journal articles. How can I solve this problem? Please help!!

Can you explain why it cannot be installed?
If it is because it is from an Unidentified developer, then just right-click on the Installer and select Open. It will then confirm you wish to open and install it.

System Profiler shows no boot volume

I have a G4 imac and I'm trying to upgrade to Tiger. It meets all the reqs and the disc is the retail full version installer. The installer freezes at the select destination screen. It shows the harddrive but it is faded out and I get the spinny thing. In the System Profiler the boot volume under Software Overview is blank.
First question is: That shouldn't be blank correct?
Second question is: Why is it blank?
Third question is: What do I do about that?

This is the discussion area for the iMac G3 CRT.

How to create and use a boot volume clone?

Hello. My name is Cassiano and I'm NOT a system administrator. I'm an architect. I design and build houses, not systems. And the reason I'm telling you that is because I need your help.
The short version of my problem is this: "How do I create a boot volume clone", but I think I need to tell you the whole story.
Here at the office I work we have 18 iMacs and 1 Xserve running OS X Server 10.4.9.
Although I'm an architect I'm responsible to keep the computers up and running.
This is not because I want, but just because I'm the one here that knows a bit more about this stuff and although I'm not an expert, I know quite a lot about this stuff. I did pretty much everything here. Configured the network, firewall, installed the Xserve, etc, but of course that if something breaks we just take the computer to apple store and wait for it to be fixed
The Xserve has 3 HDs inside. 1 at bay1 which is the boot and 2 others on bay2 and bay3. The HDs on bay2 and bay3 are working as one using SoftRAID and we use this volume to store all of our data. That is the reason we chose to mirror them using softRaid. If one fails, the other has everything and we just have to get a new one.
Last week we decided to setup the Xserve to be our mail server as well, so I turned on the Mail Service and after a lot of reading I managed to configure it correctly. In fact we have our MX records pointing to a company that relays the email to our Xserve, so it is not really accessible from the outside world.
But this Mail thing made me loose my sleep. The reason is: before that our Xserve was used only as a file repository. So if it would break or something all we have to do is take the HD out of it, send it to apple store and plug the HD on another computer. All of our files would be safe and everybody would be happy. Of course this is an over simplificated situation, but that is pretty much how it would go.
But now everything is different. Every person here has the email account configured to the Xserve, which means that if it breaks or something goes wrong, no one will be able to send or receive emails. The new messages will not be lost, because the company that relays the emails to us will keep them there, but things will get chaotic here.
When reading this document here: http://developer.apple.com/documentation/MacOSXServer/Conceptual/XServerProgrammingGuide/Articles/abpinstall.html I saw this section that said: "Cloning the Boot Volume"
Where it says: The use of the boot volume clones is entirely to ensure the highest availability possible for your system volume, not your client data.
So, finally, my question is. How do I implement this "boot volume clone"? If I buy a new HD and place it on bay4 will I be able to do that? How?
After doing it if something goes wrong how do I use the "clone volume"?
Thank you for your patience and any help is greatly appreciated.
Best regards,

Yes, your server is becoming central to your business universe. Mine, too.
Boot from DVD, and use Disk Utility to create the clone. Another way of looking at this is as a photocopy or snapshot or block-by-block copy of the state of the disk at the moment the clone is made. You can then either boot from the clone (if needed; assuming the clone is on a bootable device), or boot from the DVD and copy the clone back to the original (or replacement) disk; this restores the disk state to that of the time the clone was made.
Yes, you'll need a disk to clone to. Probably more than one, since you'll probably want to set up a rotating pool, should you need to go back to an older snapshot.
You're undoubtedly also approaching a requirement for either an add-on storage array or storage shelf via one of your PCI-X or PCIe I/O expansion slots, or adding a FC SAN into an open PCI-X or PCIe slot and adding the external FC SAN Xserve RAID configuration that Apple sells.
The external storage can be "just a bunch of disks (JBOD)" in an external disk shelf, or an external RAID via add-in eSATA or add-in SCSI controller, or via Fibre Channel for the Xserve RAID configuration for the FC SAN configuration, or (for lower speeds) FireWire or (lowest) USB.
If your data is worth it and you want to deal centrally with Apple and your budget allows it (qv: "if your data is worth it"), Xserve RAID is the way to go. The external storage shelf is certainly a feasible approach -- but you'll likely end up dealing with a third-party for the configuration, set-up and third-party storage gear.
If you're looking for things that can go wrong here, recognize that RAID only protects against drive failure. RAID does not protect against accidental nor malicious file deletions, fat-fingered operator commands, nor against application or system-level disk corruptions. RAID (only) seeks to protect against disk errors. This gets into tapes, or near-line disk copies, or other such media. External tape, or other such archival media, and particularly media that can be sent off-site on a regular basis.
It's good that you're thinking about this stuff, too.

How can I choose the volume which I want to restore by Time Machine? I have two volumes.

Does anyone know how to restore one of two volumes from Time Machine?
I have been using SSD and HDD on my MBP.Today, I replaced an old HDD to a new HDD and tried to restore from Time Machine.
Unfortunately, Migration Assistant couldn't choose which volume I want to restore.
On Time Machine, I could choose the location, but it was just a copy, not a restore.
Some files address has been changed, so I have to correct the location for every apps on SSD.
For example, "/Volumes/Macintosh HD/Users/" has changed to "/Volumes/Macintosh HD//Macintosh HD/Users/"
I want to make a new HDD be exactlly same as an old HDD, so I don't need to adjust file locations or rename the address.
Thank you in advance.

In SCORM-compliant LMSs the "mechanism" for transferring interaction data is via JavaScript variables. SCORM uses a standard JavaScript API that all compliant LMSs are supposed to understand and interpret correctly. (I use the words "supposed to" because the reality tends to be that they all interpret the standard a little differently.)
If this is a "locally developed LMS" then all bets are off. You should in theory be able to transfer quite a bit of information, but with a home-grown roll-your-own system at the other end, you have no way of knowing how it will handle that information.
You need to talk to whoever built or is currently in charge of this LMS, hopefully someone with technical knowledge and expertise. Get them to tell you how much of the SCORM standard is actually supported. Only then will you know if you can use some more advanced Captivate functionality to pass more scoring information (e.g. interaction data as well as score/pass/fail).
If your current LMS is truly only able to accept a couple of values, and your customer wants more than this, handball the issue back to them. They'll either have to upgrade their LMS or revise their requirements.

How do I know if my apps will work under Yosemite?

Hey guys, I'm running Yosemite right now on a mid-2011 Mac Mini that was originally running Lion. I then installed Mavericks on top of Lion(I didn't try Mountain Lion) and then I installed Yosemite on top of Mavericks. I'm planning on erasing the 500GB HDD and installing a fresh copy of Yosemite and then restore my apps and system preferences via an external Time Machine USB HDD I've been using for 2 years.
I'm having a spinning beachball issue that renders my Mac Mini unusable for a few minutes at a time and this is why I want to do a clean install of OSX.
So far my apps have been running great under Yosemite, BUT I'm worried that my apps are running great ONLY because I was running Lion and Mavericks before so the apps I'm running now are only working because the apps were installed onto the Lion and Mavericks 'layers'??? I haven't needed to re-install any apps since installing Yosemite.
How can I check that my apps will run under Yosemite?
Please help!

NewbMacUser wrote:
From what he said here: "Because, after you run the Upgrade, it is running Yosemite and not Lion or Mavericks."
How does that translate into this
So whatever apps I'm running at the moment on Yosemite will definitely work when I wipe the Mac's HDD?
You need to slow down and read what is being written

How can I view the boot volume permissions?

How can I view the boot volume permissions in the Terminal and/or Single User Mode?
I have tried: 'ls -l /Volumes' but this appears to only work for the non-boot volumes. I can test this by 'sudo chmod 777 /' followed by 'ls -l /Volumes' but the change is not reflected by the new list.

I prefer to have my bootable volumes as follows:
drwxrwxr-x
I see no point in allowing others to write to / and sticky here often gets in my way. Can you see anything wrong with this?
I couldn't say, as I let Mac OS X do what it wants with the / root directory. I don't know how sticky can hurt, as you need to have elavated privs to do anything in root anyway.
But if it is working for you, have fun. Just make a note to yourself somewhere that you have made this change, so that if something stops working, you can take this change into consideration. And if this change does not cause problems, but does something useful for you, you can use the note to remind yourself that you need to re-make the change when installing a new system. So take notes on your changes. It will make your life easier in the future.

How to limit servermgr_filebrowser to boot volume, to prevent 'Error getting quotas for volume'

Having a system with 1 boot drive and 15 backup drives, we do want to limit the server manager 'servermgrd' its 'servermgr_filebrowser.bundle' to retrieve/check the disk quota only on the boot volume ('/').
Because:
the backup drives are FAT formatted, which will fail every time with this error message: 'servermgrd: servermgr_filebrowser:Error:servermgr_filebrowser: Error getting quotas for volume /Volumes/I of type exfat'
the quota check is repeated every 2 hours (120 minutes), causing the log the be filled with these message and the drives to spin up 12 times a day (consuming more power than necessary and causing extra drive wear)
How can the server hard disk drive quotum check be limited to the boot volume only (not scanning for any other volume)?
And when that isn't possible, what is the correct way to completely disable servermgr_filebrowser?

Thank you Mark you are vary helpfull
Did you mean that (lower) by "bundle strategy"?
<cachestore-scheme>
<class-scheme>
<class-name>com.griddynamics.ticketon.app.dao.coherence.TicketCacheStore</class-name>
</class-scheme>
<operation-bundling>
<bundle-config>
<operation-name>store</operation-name>
<preferred-size>5000</preferred-size>
<auto-adjust>true</auto-adjust>
</bundle-config>
</operation-bundling>
</cachestore-scheme>
And if yes is it looks sense?
I mean by this, "send records to TicketCacheStore by 5000 per call " am i right?
I dropped delay to 10s and set factor to 0.5
Not coherece send me 5-20k records and cachestore handle whis successfuly.
But! By diferent means it may work longer sometimes, some lock in database for instance.
I want to find durable solution for the case, not only lower a chance i meet one.
Issuing heartbeat from cachestore looks best for me now.
I find that default guardian timeout is 65s and it is not looks as good idea to make it higher.

My MBP runs hot in the boot volume selection menu

I noticed that when I start my MBP holding shift to get to the boot volume selection menu and leave it there for 15 minutes or so (might be shorter, I was gone both times that it's happened so far) the MBP gets unusually hot (almost too hot to touch between keyboard and screen) and I can hear the fans going much faster and louder than they should be (I think). After choosing one of the boot volumes and checking the temperatures in iStat Pro I see that the CPU is at just under 70°C. A few minutes later the temperatures go down by about 10°C and the fans quiet down running at the usual 2000rpm.
Why does it get so hot? How can a simple boot menu be consuming more resources than a full desktop environment plus open Dashboard (which FYI contains 20+ widgets).

Answer: yes, it does.

How do you uninstall OS X Yosemite?

I have recently installed the new OS X Yosemite. It's nice, however, I miss my mavericks system. How do I uninstall OS X Yosemite and back to Mavericks? I have a macbook pro w/ retina, and I think I have the OS X Yosemite 10.10 because it is asking me to update to 10.10.1.

Presently, you cannot reinstall Mavericks because Apple does not permit it. What you can do is reinstall Mavericks provided you have retained a backup of your Mavericks system that you can restore or you saved the Mavericks installer when you first upgraded to Mavericks. Otherwise, you can reinstall the system that came pre-installed on your computer when it was new:
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

HP DV7-7338ea Windows 8 Unmountable Boot Volume BSOD

The product concerned here is a HP DV7-7338ea with operating system Windows 8. I have been using it for just under 11 months and bought it with Windows 8 installed.
Problem descrpition:
I recently installed a new sound update for my laptop. I was promted to restart and once that happened, I recieved a BSOD with the error message: unmountable boot volume. When that happens, it restarts and goes into "preparing automatic repair" mood after which the screen goes black and the windows cursor shows and then that's it. I am left with no options or anything. I have tried pressing F11 on start up and then it says "please wait" and goes back to the same black screen. I have left it on for over an hour but it just remains there until my computr switches itself off for overheating (this has never happened before). I haven't recently installed any thing new apart from the HP update. Please help as I do not know what to do now. I have not backed up my files yet and they are too important for me to loose. Thanks
Update:
I ran a system check and it said the Hard Drive Short DST failed. Does this mean I have lost my files? The laptop had been operating very well until this latest HP update which may have corrupted my hard drive.
This question was solved.
View Solution.

A harddisk short DST fail means that either your harddrive is failing or have failed alltogether.
If you're still under warranty, contact your retailer or local HP store and get a replacement harddrive that you can switch yourself or have it sent in for service.
If you have an IT knowledgeable friend you might be able to salvage some of the data on the computer.
You can try removing the harddrive frmo your computer and connecting it to his.
Please let me know how it works.

R61 R&R won't start after "unmountable boot volume" error

Hello all,
New user, first post - after problem, of course.
I have an R61 Thinkpad with Windows XP on it. (SP2 or SP3, not sure). Has worked flawlessly for years, then the other day I got the dreaded "unmountable boot volume" error and it would not start.
No problem - I re-start, hit the ThinkVantage button, then hit F11 to use the R&R hidden on a separate partition of the hard drive........I get the black screen with the big progress bar, ok, then a blue screen......then nothing. Hangs up and sits there. I have repeated this about 5 times now.
No problem! - I was smart enough to make an R&R CD set a while ago! Put the primary R&R disk in the CD drive, start the machine, ThinkPad button, F12 this time to choose boot from CD.....much CD activity ensues and I once again get the black screen with the big progress bar. It takes much longer, and I get teh blue screen - BUT - then it goes one extra step to display the "ThinkVantage Rescue & Recovery 4" screen with the life preserver image.
Excellent, I thing - except it then hangs there. Just sits there. No disk activity. No keys will do anything.
I can find no threads here or on any other forum with this particular issue.
Am I fubar? Or is there something else I can do?
Thanks a bunch.
Solved!
Go to Solution.

Hi jim, welcome to the forums,
Is the hard drive recognised in BIOS, was there an entry in the boot list against HDD0?
Regardless of it being shown in BIOS / boot list or not, the first thing I would do is to reseat the hard drive and see if that helps, maybe over time it's lost contact to the mainboard socket. If you don't know how to do this you can find out at the R61 movies site.
The next thing I would do is run a hard drive diagnosis check from a bootable cd, these can be downloaded from all HDD manufacturer's websites e.g. Hitachi's Drive Fitness Test. It may be that the drive has simply gone bad after all those years of work.
Let us know how you get on

Thank you and I hope you could help me solving this issue.

The file system may be corrupted. To fix it, you need to run CHKDSK on C: Drive.
If you cant boot into Safe Mode to run CHKDSK, or if the Recovery Console wont load, you may need to connect the HDD to another PC using a USB Adapter, so you can run CHKDSK on it.
Also test the Hard Disk for errors by using DFT.
DFT Download: http://www.hitachigst.com/hdd/support/download.htm#DFT
Download the ISO File and burn it to a CD-R Disc (There is also a Floppy Disk version if that's easier).
If you dont know how to burn an ISO file, read this guide: http://www.petri.co.il/how_to_write_iso_files_to_cd.htm
Restart your laptop and boot from the DFT Disc.
Choose the "Advanced" Test and let it run (it may take an hour or so).
If you see a red message box, the HDD is faulty.
An error od 0x70 means there are bad sectors and the HDD needs replacing.
