Can someone explain Disk Utility/Remove Mavericks?

I have been having problems with my iMac and want to remove Mavericks and return to 10.8. I understand I'll need to reformat my drive. Could someone explain what the problem DU is reporting and/or reinstall requirements to correct it?
Thanks
Here are the basic reference info items I am using...

You cannot repair or erase the drive you are booted from. In order to do either, you need to boot from another source: a bootable clone or your original install disks. You also need to erase the hard drive if you want to 'downgrade' back to ML. So, you boot from your disk or clone, erase the drive, and re-download Mountain Lion.

Please can someone explain how to delete email addresses? I have people who when I type in their name it comes up with the correct email address but then when you hit return to confirm it promptly changes the name to someone else (always the same someone

Please can someone explain how to delete and email address that when typed in brings up one name but when you hit return to confirm it jumps to another name. I can't find them in my contacts list but they do come up when you type the first few letters of a name.
EG If I type xyz and the name of the person comes up, when I press return to confirm that's the one I want then it jumps to [email protected], always the same def address.
I can't fathom it out.
Thanks
Terri

Try this:
Start a new email. In the To address bar, type in xyz like you normally do, press return to confim, and when the address you want to remove shows up in the address bar, move your cursor over the address you want to delete.
A small triangle next to the name will show up. click on it, a drop down menu will open, click Remove from Previous Recipients List. Then do the drop down menu again and Remove Address.
Good luck.

Can someone explain how data is fed to the usage details screen in My Verizon?

Can someone explain to me how I can view my data usage for a past date today and when I look at the same date a few days from now there will be additional data. Customer support were adamant that the data usage details come directly from my device so I commented that my device must be saving usage and sending it to Verizon arbitrarily to which I was met with silence on the line.
Here's an example - on 4/1 I checked my data usage details for the date of 3/21 and it looked like this:
03/21/12
08:43:00 PM
0.02518
03/21/12
09:17:00 AM
0.01475
03/21/12
07:20:00 AM
0.01730
then on 4/7 when I checked my data usage details for the date 3/21 it looked like this:
03/21/12
11:45:00 PM
1.15382
03/21/12
11:38:00 PM

The red rows have been added between 4/1 & 4/7, but where did they come from? This is just one example, it's happening all over my bill and Verizon cannot justify the anomaly and certainly won't consider removing the $40 in overage charges I have this month. Which brings up another question, why doesn't Verizon offer more than 10GB for the mifi? If I want to use more data and am willing to pay for it, I have to go to another provider?

Hi kellieh,
When you had your data overage (and the additional spurious charges), how did Verizon respond to you?
I have just reported a 2x discrepancy between individual device data usage (.89 GB total) and the reported 1.5 GB for my account. They claim it will take 72 hours to get back to me after they research the problem.
What avenues did you pursue to make contact?
I caled 611, then emailed tech support, then sent a private message to Verizon Wireless support.

Can someone explain "copy address" in Mail?

I have never understood why when you click on an address in an e-mail and then select "copy address" what you get is not only the address but also the name. For instance, "[email protected]" when you copy and paste yields "Name <[email protected]>". This is a royal pain because if I for instance want to paste this in another application like in the address field for Evernote to send a note to someone, I then have to manually remove everything but the actual e-mail address.
So can someone explain why Mail does it this way? What am I missing? Is there an easier way to copy just the e-mail address that won't give me the extra crap?

Outstanding! And I love the commentary, "incredibly irritating". This is one of those, "what were they thinking?" changes. There must be some logic behind the change but I have never figured it out.
Glad someone figured out how to fix it.

Network Installer: Can't run Disk Utility

Hi, all.
Just created a net install image. SIU's log did not report anything out of the ordinary, however for some reason I can't run Disk Utility, and I need to as the automated installation options frequently don't work.
I select Disk Utility from the Utilities menu and nothing happens.
I run the Terminal and try hdiutil and get
dyld: Library not loaded: /usr/lib/libbz2.1.0.dylib
Referenced from: /System/Library/PrivateFrameworks/DiskImages.framework/Versions/A/DiskImages
Reason: image not found
Trace/BPT Trap
Now, if we mount that image on a running Mac we can see the following
bash$ ls -l /usr/lib/libbz*
-rwxr-xr-x 1 root wheel 138436 Nov 1 11:33 /usr/lib/libbz2.1.0.2.dylib
-rwxr-xr-x 1 root wheel 138444 Mar 4 10:19 /usr/lib/libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.1.0.dylib -> libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.dylib -> libbz2.1.0.3.dylib
If we run the same command on the netbooted machine
bash# ls -l /usr/lib/libbz*
-rwxr-xr-x 1 root wheel 138436 Nov 1 11:33 /usr/lib/libbz2.1.0.2.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.1.0.dylib -> libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.dylib -> libbz2.1.0.3.dylib
So it looks like libbz2.1.0.dylib is symlink'd to libbz2.1.0.3.dylib, except libbz2.1.0.3.dylib doesn't exist in the netbooted image. But it does exist in the image when it isn't netbooted! Yes, they are the same image!
I also have two "Help" menus, just for kicks.
Does anybody know what's going on? I guess I'll re-create the image, but it'd be nice to understand what's going on and know if it's something I can somehow avoid in the future.
On the lighter side, this is the first time in nearly a year I haven't had to manually insert the CoreVideo.framework to get the image to boot!

Ah, forget what I said about it being the same image. I didn't notice that my chroot hadn't worked when I was checking... I was checking the live system instead. Good thing, too, 'cause that was just TOO weird.
Still doesn't explain why there's a link to a non-existent file. To test I created a symlink for libbz2.1.0.3.dylib which just points at the previous version. Guess what: Disk Utility works now.
I'm re-creating the image anyway and we'll see if the problem exists on that one as well. If it does, I won't be pleased. That'll be two repeatable bugs that break the NetInstall function for me in a year. Not cool.
Anybody else getting weird output if they type hdiutil in to Terminal at the Network Installer? Or do you have a non-working Disk Utility?

Can someone explain to me Vector Class !!

Can someone explain to me, or tell me where I can find a good tutorial about Vector class.....in simple terms....any good simple, easy to understand tutorials???
Thank you.
Rod

Start with this:
http://java.sun.com/j2se/1.4/docs/api/java/util/Vector.html
Essentially, a vector is a single Java object that allows you to store a group of similar things. Each item, or element, inside the Vector must be of the same type, or Java class. The important thing to remember about Vectors is that their size is not fixed. If you don't know how many items you need to store in advance, a Vector is a useful datastore, because you can simply add items into it without worrying about reaching the maximum size. The Vector object will grow itself as you add elements.
The important methods are described in the above API. Read through it carefully.

Can someone explain how .prel files work?

Can someone explain how .prel files work? My C drive is O/S and programs, my D drive is storage and the project file(s) (the .prel file) are on my E drive.
How is this supposed to be more efficient/faster? P.E. (C drive) has to constantly communicate back and forth across drives with the .prel file and all the files in the subfolders? It seems like it would be slower.
As I mentioned in a previous post; my zooms in/out of the Timeline are VERY slow. It is almost 1 second before the Timeline gets bigger/smaller. Any info would be great,thanks!

By using multiple HDD's, one is spreading the I/O (Input/Output) load over various HDD's. The controller is faster than a single HDD, being tasked to read/write from/to multiple places. One of the first laws of physics is that an object cannot be in more than one place, at the same time. The heads on a HDD are no different. If requests for multiple reads are made, the heads will position themselves over on place on the platters, read, and then move to the next requested location, and so on. However, with multiple HDD's, and a good, fast controller, the heads of each HDD will be placed, where necessary, so reads are done at once, from multiple locations.
For ultimate performance, a good setup would be as follows:
C:\ system OS and programs (more reading being done here, than writing)
D:\ Project files (PREL's in this case)
E:\ RAID 0 Scratch Disks for Media Cache, but not Render files (both reading and writing)
F:\ RAID 0 Media files (more reading, but also writing)
G:\ RAID 0 Export/Share and Render files
Some go so far as to separate out Audio Assets from Video Assets, and use a separate RAID 0 for each
The downside of that "ultimate performance" setup, is that when a Project is completed, to clean up, one has to go to many HDD's, and locations. There can also be issues when Archiving a Project, because things are scattered about.
I get "good performance" by having my Project, Copies of my Assets and all Scratch Disks on one HDD. What I give up in performance, I make up for with housekeeping chores, when the Project is done. I still spread my OS/programs from my Projects, with separate physical HDD's.
Good luck, and hope that this helps,
Hunt
PS - Above, I mention RAID 0, but even greater speed can be achieved via many HDD's in the Array, and perhaps a RAID 50. RAID 0 is just two physical HDD's. Also, for RAID, I recommend a dedicated RAID controller card, and NOT software, or the MoBo's RAID capability.

Can someone explain how to set up an administrator account so that I can have my phone and my daughters have separate apple ids?

I mistakenly updated to the latest version of iOS and ever since then I can send messages to my daughter and I receive them but she does not. She has an iphone also and her phone is under my apple id also. Someone told me that I could set up an Administrator Account so that she can still be under my account but she has her own ID and that will fix the problem with text/imessages. I can't find anything on the website that explains how to do that. Can someone explain that to me?
Thanks!

I'm still not clear on what you are trying to accomplish. If you have an iPhone and she does as well you should have your own Apple IDs.
If you want to pay for any purchases she makes with her phone as far as apps/music goes than that is what Family sharing is for.
In my case my Wife and I are setup for family sharing. When she purchases music/apps it charges my credit card. This setup also allows me to share my past music/app purchases with her and vice versa.

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported. Is this a bug in Mavericks?

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported.
This happens not just with the SSD in my Mac Mini, but with another SSD in my MacBook (both now running Mavericks). So far as I know, all of the kit I am using is in good order (despite the file corruption reports). So I am beginning to wonder if it could be due to a bug in Mavericks? Both SSD drives have been formatted to MacOS Extended (journaled) format. Should I have used a different format, I wonder?
Has anyone else encountered this issue?
Does anyone have a solution?
Or an explanation that might help my investigation of the issue?
Thanks guys,

I understand that the Corsair Force 3 is not one of the SSD drives that are supported on Apple Macs.
I did try downloading and using Trim Enabler, but the error message came up both when it was off and when it was on.
I understand that not everyone thinks Trim Enabler is a good program, though there is a new version out now, so I may give it another try.

Can't get disk utility to work with leopard - iBook running super slow

I have an iBook G4 and it's running ssuuppeerr slow but I can't get disk utility to come up after I press C down. I don't know if I'm pressing it at the wrong time but I restart with the C pressed and it gets to the apple screen and it won't go anywhere else. It will restart normally but not with the C key. I've been trying for an hour and I can't get it to get to disk utility!
Any help is greatly appreciated!
Thanks
Annie

Welcome to Apple Discussions!
Do you want Disk Utility on your iBook or do you want Disk Utility on your install disc?
For Disk Utility on your iBook, go to Finder>Applications>Utilities and look in the Utilities folder. You will find Disk Utility there, and drag it to your dock where it will be handy to have it.
For Disk Utility on your install disc, insert the install disc and then restart and hold down "C" as you boot up so that you will boot from the install disc. Then choose your language, and then look for Disk Utility in the menu bar--I don't remember if it says "Utilities" or "Disk Utility". If you need to repair your startup disk (i.e. your internal hard drive), you would boot up from the install disc to do this.
However, I am wondering if you have enough RAM to run Leopard. You will get a big boost in performance if you max out your RAM. Leopard will run best if you can put a 1 GB RAM stick in your RAM slot.
If you want to repair permissions after installing and updating Leopard, you can do this with Disk Utility on your iBook. Repair permissions until there is nothing left to repair.
If you have more questions, please post back. Also, which ibook G4 do you have?
Good luck!

Trying to understand RSTP - Please can someone explain this?

Hi Group
I am still confused about how RSTP is implemented. From what i understand the major difference is that STP
used Timers for Loop prevention whereas RSTP coordinates between neighbors via messages (proposal/aggreement) to turn on links
more quickly after topology changes and is "timer free".
However, I have not noticed any difference in the configuration from the legacy STP
configurations and the RSTP configuration on cisco devices. Or are there any differences??
I have read in documentation that RSTP natively includes features like UplinkFast, BackboneFast and PortFast. So are these features now obsolete
and not needed to be configured if you are running RSTP. (Although i have seen Portfast still configured along with RSTP on many switches)
Also can someone explain the below Points from Cisco Documentation
1) should STP be disabled on edge ports all together as suggested below?
"STP edge ports are bridge ports that do not need STP enabled, where loop protection is not needed out
of that port or an STP neighbor does not exist out of that port. For RSTP, it is important to disable STP
on edge ports, which are typically front-side Ethernet ports, using the command bridge
bridge-group-number spanning-disabled on the appropriate interface. If RSTP is not disabled on edge
ports, convergence times will be excessive for packets traversing those ports."
2) It seems RSTP relies on duplex setting to determine inter-switch links. What is the configuration to explicitly
configure RSTP link types? (I couldnt find this in the documentation)
"RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to-point links.
The link type is automatically derived from the duplex mode of a port. A port that operates in fullduplex
is assumed to be point-to-point, while a half-duplex port is considered as a shared port by
default. This automatic link type setting can be overridden by explicit configuration. In switched
networks today, most links operate in full-duplex mode and are treated as point-to-point links by RSTP.
This makes them candidates for rapid transition to the forwarding state."
Also i am a bit rough on my RSTP knowledge even after skimming a few Cisco documents. Can someone please explain this in simple way.
Thanks in advance

to configure it on a device:-
spanning-tree mode rapid-pvst
PortFast/UplinkFast & BackboneFast were cisco "Enhancements" to 802.1d STP. RSTP just incorperates them. If you want to configure portfast, the command is still "spanning-tree portfast"
OK
1) That is your choice - I have bitter experiance of users/IT admins just plugging hubs/switches in when ever they can. Also cabling the switch back to itself creating a cabled loop. So my advice to you is to leave STP enabled on all switch ports, BUT enable BPDUGuard - this is a life saver, if you have configured portfast.
2) duplex auto! or duplex full (overiding)
I really suggest that you read the 802.1d standard, once you understand normal spanning-tree - RSTP will come to you.
