Hi
I am going to be buying a macbook air 2012 model with 4 GB ram soon. I was wondering how much space (memory) does Norton AV take up and does it drastically slow down the computer. Also, I am going off to uni so will predominantly be using the laptop for surfing and MS office.
Thanks a lot

Sorry to disagree mende1. In this age of email attachments and social networks, it is actually a good idea to have a good antivirus on your system. {I realize that this is a religious argument and I will say no more}. With that said, the general concensus is that Norton AV is terrible. It is intrusive and uses up a lot of cycles.
There are a lot of better AV clients out there. I use ClamXav which is free and uses the clamav antivirus that is open source.

Can a 128 ssd storage still effectively work if I install windows 8.1 plus msoffice and a window-based proposal system? I plan to buy a macbook air entry level with 1.7 gh i5 processor.

If you are going to use Mac OS X and its associated applications, and a BootCamp partition with Windows 8, and MS Office and all of the work created there, you will more than likely run out of space on a 128 GB SSD pretty quickly...especially if you put any music, photos or videos on it. Those things take a lot of space so you will have to be very, very careful about what you want to put on a 128 GB storage space. You would be better off going for 512 GB with what you plan on doing with it.

How much memory/space are Mac Apps Taking?

I know this is probably a very simple question for you experts but as a newbie, I dont know how to figure it out. Im trying to find out how much hard drive space (and maybe memory?) the apps I have downloaded from the Mac App Store are taking up? Where would I find this? Ive looked in the Finder but couldnt find what I was looking for? Does the Activity Moniitor or something else break it down to just the Mac Apps?
Also do you know if Time Machine saves your organizational Launchpad Folders when you back up your machine? Just was curious if you had to switch macs or something, if the folders would all come back up or if its best to keep a list of what apps you have in what folders.
I also was wondering if anyone else has had a problem of your Launchpad Folders and individual apps within folders getting out of order when you have to restart your system. Since I dont yet have an iphone and apps were new to me, I got a little crazy in downloading a bunch of free apps and games (many of which I think Im going to start deleting because I dont really use them)...but Ive organized them in all in alphabetical order - Ive got folders in Alphabetical Order as well as the apps within folders in alphabetical order. Its strange becuase whenever my system gets restarted, several of the folders and apps get mixed up. Ive been working with Apple techs on this for weeks but just curious if anyone else has had a similar problem. The tech told me most people dont keep it as well organized as I do.
Thanks.

To find out how much hard drive space (or how large the App is), Right-Click on the App in your Applications folder and choose Get Info. This will show you xx MBs on Disk (hard drive). To see how much memory the App is using, check Activity Monitor while the App is running. It will be on the list of all processes running.
But you can also click the  (apple) in the upper left hand corner of the screen and select about this mac>more infor>storage

How do I see how much memory is being taken up by programs and how do I delete the ones I don't need.

Is there a way I can see how much memory each program is taking up and then how do I delete the ones I don't want to use.

Download from the Internet OmniDiskSweeper (free) and open it. It will show all of your files and the respective sizes. Delete and transfer what you do not want or need on your HDD.
Ciao.

Hundreds of DMProxy processes slowing down the Mac

Hi all
(now posted as a separate question)
I've got the following problem on my MacMini with OS X 10.3.9. and tried a lot of things (permissions, harddisk repair, PRAM reset, Startobjects remove...) nothing worked...
After a while after login (sometimes seconds, sometimes minutes, but seriously always after a while), usually reproducible when starting "large" programs like Adobe Photoshop after a few seconds, the mouse and screen update rate sink immediatly to once in 5 to 10 seconds and all processes are slowed down similarly. No work is possible afterwards, not even killing some processes or restarting the mac by key-stroke.
I used "top" from the beginning and could see (after a few minutes of "not-refressing") a lot of DMProxy (with UID 0) processes (100-1000) blocking my systems, when this issue has occured.
I even don't know which process has started these DMProxy's, so this posting is my last help, before reinitializing the whole system - I still don't know, how this could happen.
Any suggestions - how to get rid of this DMProxy's
Best Regards, Rico

Hi Pan,
Sysbase infocenter SyBooks Online and SAP note: 1982469 - SYB: Updating SAP ASE with saphostctrl / sapdbctrl and 1590719 - SYB: Updates for SAP Adaptive Server Enterprise (SAP ASE) are the starting point to cover the update.

MacScan - Does it slow down the Mac?

Hello!
I was looking at possibly installing MacScan but wanted to see what others thought first.
I am relatively new to Macs. On my PCs I've had antivirus software before but one thing I disliked about any antivirus software was it always seemed to reduce my performance...everything ran slower because the stupid software was always running. I hated it.
Does MacScan work constantly??
Has anyone noticed it slowing their machines down?
Is it possible to say load it- run a scan - and then remove it completely off the computer?
I am curious to know what you all think.
Thanks!!

Does MacScan work constantly??
No.
Has anyone noticed it slowing their machines down?
No (see above!)
Is it possible to say load it- run a scan - and then remove it completely off the computer?
Yes.
No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download from:
http://www.clamxav.com/
However, the appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)
A white paper has recently been published on the subject of Trojans by SubRosaSoft, available here:
http://www.macforensicslab.com/ProductsAndServices/index.php?mainpage=document_general_info&cPath=11&productsid=174
Also, beware of MacSweeper:
MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008
http://en.wikipedia.org/wiki/MacSweeper
On June 23, 2008 this news reached Mac users:
http://www.theregister.co.uk/2008/06/23/mac_trojan/
More information on Mac security can be found here:
http://macscan.securemac.com/
The MacScan application can be downloaded from here:
http://macscan.securemac.com/buy/
You can download a 30 day trail copy which enables you to do a full scan of your hard disk. After that it costs $29.95.
More on Trojans on the Mac here:
http://www.technewsworld.com/story/63574.html?welcome=1214487119
The latest news on the subject, from July 25, 2008, is:
Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.
The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.
In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.
Net security groups say there is anecdotal evidence that small scale attacks are already happening.
Further details here: http://news.bbc.co.uk/2/hi/technology/7525206.stm
A further recent development is the Koobface malware that can be picked up from Facebook (already a notorious site for malware), as reported here on December 9, 2008:
http://news.bbc.co.uk/newsbeat/hi/technology/newsid_7773000/7773340.stm
You can keep up to date, particularly about malware present in some downloadable pirated software, at the Securemac site:
http://www.securemac.com/
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac, and alternatives will probably appear in the future. In the meantime the advice is: be careful where you go on the web and what you download!

Is an external hard drive the best way to keep tons of photos and songs, or does it slow down the mac too much to retrieve it?

I have an old Macbook that has a bunch of pictures and songs on it, but few videos. What I do have is slowing it down, particularly iPhoto - I sometimes have trouble editing pictures because the RAM just isn't there (I have it maxed out at 2gb), or even organizing them. I have thought of moving my pictures off the mac onto a hard-wired external drive, but have been told it makes mounting iPhoto even slower to do so. What do people do that have many thousands of pictures?

Install software such as Paragon NTFS. Regardless of the method you use, back the data up; that drive may fail at any time.

Looking to buy new MacBook Pro for editing with Premiere/After Effects, but wondering about trade-off between Processor Speed and Graphics Card

I'm a professional video editor (using Premiere and After Effects) looking to buy a new MacBook Pro and am deciding between two models. The slightly older model has a 2.8GHZ i7 (3rd generation) Quad Core processor with a 1GB SDRAM of NVIDIA GE FORCE GT 650M Graphics Card. Then newer model has a 2.3GHZ i7 (4th generation) Quad Core preocessor with 2GB SDRAM of NVIDIA GE FORCE 750M/Intel Iris Pro Graphics Card.
Which makes the most difference (processor speed vs. graphics card) with editing with Premiere and After Effects?
Any help/guidance would be greatly appreciated.
Thanks!

1. Your MBP will be somewhat slower than your iMac, as reflected in the general speed; desktop Macs have more RAM and storage.
You recon? If he get's the 17", he would have up to 8x more RAM, 4 x more GPU,, and a bit faster CPU;.
2. Be aware of the advantages and disadvantages of extra RAM. Loading up the slot will make juggling multiple applications easier, like Photoshop, VLC, and Safari. However, more than 4gigs of RAM will make loading your MBP on startup twice as slow - at least a minute, probably longer. That's why a MBP user with extra RAM should sleep their machine nearly always when not in use, rather than powering off.
I did not know this, I just upgraded from 4gb to 8gb the other day. Have not noticed it being slower, but I don't often shut it down. It's nice to not even have to bother with ifreemem.
3. Additional storage and RAM will maximize the basic capabilities of your MBP, but you won't be able to make a 2.3ghz machine any faster than it already is.
SSD
4. I still feel that your iMac will be faster than your prospective MBP. The only way to dramatically increase the speed would be the installation of a SSD drive (like the lauded OWC series). But they're not cheap.
I don't want to rain on your parade, but want you to get a more realistic idea of your performance.
I chose a macbook pro, 17" of cause. I use it for gaming. Yes a iMac is better for gaming. But, it's nice to be able to move around. Set up a man cave in the lounge 1 week, or in the bedroom, the next. But you fork out a lot more dosh for that luxury. And yes, not as much power as Poikkeus has said.

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overal performance?

The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter.

I just upgraded to Maverick on my2 year old Macbook Pro and it has slowed down the computer terribly. All I see is that whirling circle every time I do anything. How do I go back to old OS. Terrible upgrade -- forces you to buy a new Mac!!!!

It does not. First things first have you tried restarting?
Try restting PRAM

Try booting up in Safe Mode

Also open "activity monitor" and look and see what is using a lot of processing power.

TS2570 I have MacBook Air late 2011 with encryption enabled the mac froze so I just shut it down by pressing the power button .But the when I tried booting the gray screen appeared nothing else

I have MacBook Air late 2011 with encryption enabled the mac froze and I pressed the power button to shut it down but then the gray screen appeared no wheels nothing just gray. I tried all steps but nothing helped. Worse than that only the pram key combination works I cant get the cmd-r or just alt or any combination to work??? Any suggestions would help. Thanks!
P.s. I am on mountain lion with ssd encryption enabled. The mac froze when the internet stopped the one from the cable (I use ethernet usb one) when I turned wifi on it froze. I have disconnected everything when trying the steps except power cable.

Boot into Internet Recovery (command-option-R at the startup chime) and try to repair the boot volume in Disk Utility. You will have to unlock the volume before you can do anything with it.

Is it possible to shut down the MAC automatically while being in sleeping mode?

Dear all,
on my MacPro I use a setting that after 30 minutes of inactivity, the machine moves into sleeping mode. That works well.
Additionally I'm using a setup within the energy saving section, that the Mac should shut down every day at 10:00 pm and start or wake up every day at 07:00 am.
But it seems, that, if the Mac is in sleeping mode at 10:00 pm, he cannot shut down.
Does anyone has the same experience and/or knows any help?
Thanks in advance - helee29

Dear Martin,
Thanks for reply.
I checked the logs as mentioned, but honesly saying I'm not experienced enough to understand all this notices.
What I found out in the meantime by testing (try and error) is:
- if the Mac is in working mode (just the screensaver is working) the automatic shut down and restart to set times works perfectly.
- if the Mac is in sleeping mode, it doesn't shut down automatically at the set time, but makes an automatic restart at the set time
Ergo there is a problem to shut down the Mac automatically while in sleeping mode, but I still don't know what it is.

When I shut down the Mac Pro, it restarts

Has anyone run into this issue with their Mac Pro? When I shut down the computer (either via the Ctrl + Option + Cmd + Eject or the Shut Down command from the Apple menu drop down), the Mac Pro will simply restart and take me back to my log-in screen.
At this point, I can hit the shut down button on the login window and it will shutdown, but this is annoying, a waste of time, and unnecessary.
I have tried performing an SMC reset, but it has not resolved this issue.
Specs: Mac Pro (2010)
3.33 GHz 6-Core
(2) 2TB Internal HDD
12GB ram
ATI 5870 graphics card (1GB)

I have noticed the exact same behaviour. It only happens when I have something plugged into one of the front USB ports (example : external HD, USB key)
Apparently the system crashes during the shut down process, and then reboots.
Unfortunately, I have not yet found a solution

How can i fix my mac book pro i bought in mid 2010, it is slowing down. the pin wheel does spin a alot.

how can i fix my mac book pro i bought in mid 2010, it is slowing down. the pin wheel does spin a alot.

try this;
open disk utility - verify disk permissions - repair disk permissions if errors are found. might take an hour or less - depending on how much errors needs to be repaired.
restart your macbook and see if that sorts it out for you.
also check your hard drive space. if your hard drive is almost full, that will also contribute to your macbook getting slower....
good luck

What is this all about? "The "QuickTime Plug-in 7.6.6" plug-in is slowing down your Mac. You can wait for it to recover or stop it now." I'm running Mavericks 6.8.

I regularly get a prompt reading as follows: "The "QuickTime Plug-in 7.6.6" plug-in is slowing down your Mac. You can wait for it to recover or stop it now." I've tried waiting, but nothing happens. I "stop it now" and lose the page I'm reading.
