Copying painstakingly slow and hogs the machine
Hello everybody,
I have an issue with copying files on external drives. This especially related to backup. When I am copying files from one external drive to the other my OS slows down to a halt. As you can see on these images:
http://www.interiority.com/misc/progress.jpg
http://www.interiority.com/misc/CPU.jpg
The system takes utterly complete control over the machine and I can't do anything (except doing it very slowly), and it takes a very long time even though I am copying from one external FW800 500GB disk to another (1TB disk). This also affects my backup program (Super Duper!) and backing up approx. 500GB from one disk to another can take up to six-eight hours!! How come?!?
I am taking good care of my machine - run Cocktail once a week, using Disk Warrior after every crash, always keep my system up-to-date etc. and all disks' S.M.A.R.T. says everything is a-ok (the drives are brand new except for one, but there's no difference in speed).
Why is it so? And why does any form of copying hogging the system up to 90-95% without me being able to do anything about it?!? This is getting very annoying! Help!

Surely you meant to say that there was nothing in Lion you would prefer over !10.6! - Lion is 10.7.
As for what might be sapping your machines juice - have you run Activity Monitor yet? I always enable 'All Processes' and sort it by %CPU usage if i want to know whats cooking.
In addition to the list Disk Activity might give a hint.
If you are quite low on available disk space it might also be that osx is constantly swapping - best to keep a few GB of free space for it to work with.

This is not a question. I believe I've found a new issue and the fix for it.
The situation:
A brand new iMac 27" running Yosemite 10.10.1
MacMini server running 10.8.5 server.
The issue:
Client on iMac trying to work on MS Word documents stored on server was requiring him to save the documents to his desktop and then copy them back to the folder on the server. The exact error message was, "This file is read-only. To save a copy, click OK, and give the document a new name in the save dialog box."
The issue is unique to this computer in an office of 10 client computers and three servers.
Attempted fixes:
Verified that the ".Temporaryitems" folder existed and the permissions were set properly.
Repaired permissions on the client and the network share.
Definitive fix:
By default, Yosemite 10.10.1 uses SMB for connecting file shares. When I overrode the default and switched to AFP protocol, the issue went away.
I hope this helps someone else.
RobThat was it. What an operating system. It is very helpful to view files you are looking for. But if you have preview on you cannot save files.

Trying to restore after getting a new hard drive. I can see the backup on the Time Capsule and on the correct date but it is Greyed out. That is it wont let me open it and restore the machine. Have tried also Migration Assistant, no luck.

At startup hold down the Command+Option/Alt+r keys until you see a globe on the screen. Then use disk utility to partition and format the drive HSF+ and then select Reinstall Mac OS X. whatever version of OS X that originally came on your system will be installed and then you can upgrade back to Mavericks. -
Since loading Lion, I've experienced much more instability than Snow Leopard. In particular, Mail crashes with regularity, full-screen apps seem to run slower and show the beach ball more often for longer, etc. I love the features, but I'm disappointed with the performance. Any help coming from Apple? I've been sending them so many reports after crashes, that their file must be full!
Summoning max. courage, I did what you advised. Here is the result. What does this tell you? My Lion 7.2 (mid 2011 iMac) has several annoying glitches (which I have so far tolerated through gritted teeth) but none that have actually stopped me working.
BTW, I see several items involving CleanMyMac which I did not know I had. It is generally villified as a trouble-maker. Spotlight can't find an app. or a utility of that name. How can I get rid of what's there please? Just delete?

I recently downloaded my digital copy of titanic and from the itunes extras screen I push play and nothing happens. The movie is not listed, only the itunes extra is listed in the list. How do I repair?
I have the same problem on the latest iTunes software and Windows 7. My window is maximzed and I do not see any tab for photos. Seems related to a recent update (IOS7?) as this was there - at least before the very big change to the interface.

In Numbers, I copied a worksheet and deleted the contents. The sheet I copied has a header. I can't see it or bring it up when I'm working but it appears when I print the sheet. How do I delete the header?
Hi Cristina,
Headers are not shown in normal view.
Menu > File > Print to open Print View.
Hover the cursor over the Header to see the outline. Click and delete.
Regards,
Ian. -
Copy my music and all the album art
I am going to reinstall my computer, but I want and copy my music and all the album art on a hard drive, so I wonder if it is possible to copy all your music and album art that is iTunes into a hard drive?

I have a MacBook Pro (purchased in 2011) with OS X Lion 10.7.4. I'm using Microsoft Office 2011 and cannot open older PowerPoint Files (non .pptx). It will always open the same .pptx file and then the machine hangs up and just keeps spinning.
Thank you - that all makes sense. It is, indeed, exactly what I did when I upgraded.
I'm also writing this on the machine that crashed a few minutes ago (I posted the crash in another thread). I got back with a 'safe boot' - as I have done a few times before.
I've also de-installed little snitch (and then done a safe-boot & then re-boot ) since that seemed involved. I de-installed Adobe flash, since that seemed to be a problem - I then re-installed the later, apparently fixed, flash. The most recent crashes don't seeme to have a problem with flash any more.
I've posted the various ( generally different ) crashes. I also posted a summary of the similar lines that turn up in most of the crashes.
Unfortuantely, I'm actually trying to use the machine to meet some urgent deadlines and all this is not making it at all easy.
I had had great hopes for 10.7.2 - I thought that the crashes must be pretty common, so would have a common aetiology. There do seem to have been some fundamental changes to the file sytem and to the video interface (that seems to cause problems to brand new iMacs as well as to my 2009 iMac). -
I am using a Mac with OS X 6.8 it has 2 gig of ram and it keeps freezing. Tlhe mouse will move but the machine is frozen, if i shut down and restart the machine is fine for a while. any suggestions as to what to check or what could be causing this?
Run Disk Utility to check the SMART status of your hard drive.

Hey, my macbook pro started going slow out of nowhere and gets the loading wheel often, I can't close it without the charger attached otherwise it heats up real bad. I've been told to get a hard drive and back up everything through time machine and then reinstall it but wouldn't that just carry over whatever problem I'm having. I've tried everything that I've found on here like going into disk utility and repairing anything broken, I checked my memory and all that and it was good but I deleted anything unnecessary and put all my music and movies onto an external hard drive.
If you don't already have backups, and you have any data that you want to keep, shut down the computer immediately and don't turn it on again until you have at least one external hard drive to use for backing up. Then see below.

Hi,
I bought a new Mac Book Pro a couple of months ago the new model, very high spec, i7 processor, 500g solid state drive, 8 gig of ram. all in all a very fast machine. however, i foolishly downloaded OS X Lion and as soon as i did i noticed a considerable difference in the machine basically its ground to a halt, its now slow glitchy programs shut down and crash. I'm new to Mac and in reminded of life in the world of Windows....! any suggestions should i wipe Lion off the machine and re install Leopard? any help would be appreciated..

I have a laptop with Windows 7, and when the machine is turned off it loses all the user names
I have a Gateway Laptop with Windows 7, 64 bit. When the machine is turned off, and then
back on it loses all it's user names that have been remembered.Do you mean names and passwords in the Password Manager or do you mean that you are no longer logged on to (remembered by) websites after closing and restarting Firefox?
There is a difference between remembering the name and password in the Password Manager and a "remember me" check box on a web page to log you in automatically.<br />
The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and that is send to the server.<br />
If that "remember me" cookie is removed or gets corrupted or is not send to the server then the server won't remember you anymore and you need to sign in once again.
In case you are using "Clear history when Firefox closes":
*do not clear the Cookies
*do not clear the Site Preferences
*do not clear the Saved Passwords
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
*https://support.mozilla.org/kb/Clear+Recent+History
Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.
Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception. -
I copy a row and then the next row as no actions
I know this is easy.
when I set up actions in a row and try to copy it and past a row below it is not there.
can anyone help?Hi,
One of the easiest ways to do this is simply select the row (discussion below about selecting) and hold the "Ctrl" + "D" ("D" is for "Duplicate"). This will duplicate the row and place it directly under it. Also, you can use "Duplicate" by clicking Edit>Duplicate
Selecting rows can sometimes be tricky. If I use the mouse, I always try to confirm in the Object and/or Hierarchy Pallet.The mouse can select the row (arrow with an underscore) or all the objects in the row (arrow no underscore)
Here are 3 ways:
The mouse can select the row (arrow with an underscore) or all the objects in the row (arrow no underscore). You move the cursor just to the left of the table and the arrow appears.
One of the best ways I find is selecting the row in the Hierarchy Pallet.
Select an object in the row and on the tool bar click Table>Select>Row
I avoid pasting anything if I can help it. If you use flowed forms and if you paste a lot, and If you aren't careful, you'll end up with a corrupt form. Designer is very unpredictable about where it will paste. If you have a large form, it can take a minute or two to track down a pasted object's location. Then you have to move it to where you want it.
Better to use "Duplicate". That usually means it will be next to the item you're duplicating. If you copy and paste, paste, paste repeatedly too fast, You can really mess things up. Every Paste command takes longer than you think to execute. Wait at least 2 seconds before doing anything after pasting. Otherwise, you'll interpt Designer while it's busy writing the new XML. Yes, Designer is still busy doing work even after you see the new item appear. Be patient.
Good luck!

RC2 is not an improvement for me. The sliders (particularly the Transform ones) are now slow and jerky in response. Furthermore, RC2 seems to accumulate RAM space as time goes on, and progressively slows down as it does so. The only way to get it to relinquish RAM is to exit. I wasn't having issues before - RC1 was fine. Now I am ...
Windows 7, 8GB, Intel Q8400I have the original problem. Firefox works great when all of its windows are open on my laptop's LCD screen. (It's a Lenovo T420s.) When I move a FF18 window even partially onto the second monitor, and then move the mouse within the window, CPU utilization spikes. The mouse tracking is "sticky" when the pointer passes over menu elements and links that have visual mouse-over effects; that is, the pointer stops while the button or menu appears and then jumps to where it should be. The overall effect is so annoying that I have to keep all my FF windows on the primary (integrated) display. This first appeared in FF18 and continues in FF18.0.2.

My original iPad is slow and drops web pages and videos all the time now. Is the software just too old to handle the technology changes on the websites and video or is it a virus or junk in the iPad causing this? I have plenty or storage left on the iPad like 18GB. Sure would like to know. Maybe it is just too old to handle things now?
IIf you are running iOS 6.1.2, you could not be using the original iPad. No matter which iPad and what version, try these basic troubleshooting steeps and see if it helps with the performance.
Go to Settings>Safari>Clear History and Website Data. Then close all apps.
In order to close apps in iOS 5 or iOS 6, first tap the home button once. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button twice.
In order to close apps in iOS 7 or 8, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Now reset your iPad. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
You can also try resetting all settings. You will not lose any data, but most of the device settings will have to be entered in the settings app again. Settings>General>Reset>Reset all Settings.
