Do OS X updates use a lot of power?

After I did the patch update for my MBP on Tuesday, I had @70% battery power left when I put it to sleep. Tonight, about 24 hours later I had 11% left. I did that update right after it was available, around 2PM ET. I was using an external battery (HyperJuice) to my MBP to increase between AC Charges.
The last update before this one also drained my battery AFTER the update, when I put it to sleep.
Should I have shut it down instead after the updates were complete?

That sounds like an unusual problem. I applied the update and slept it as usual and the battery was at a normal level the next morning. There is no published advice to shut down after updating, other than the required restart.

Texting and just being in the HUB uses a lot of power. Help, please!

First let me say that if any BlackBerry rep posts that useless battery saving guide in response to my question, I will flip.
Being in the hub uses 1-1.6 watts of power which is the same amount that facebook or twitter uses, if not more. This should not happen. I've tried to contact via twitter the BlackBerryHelp people but they never got back to me. There is no 1-800 number. I'm asking everyone if this is normal? I have done every single battery tweak I can and this is still happening. I am at my wits end. I can watch the battery percentage tick away while composing an email or a text. I have two batteries. Both experience the same drain. Thank you for your time

I haven't experienced serious battery drain on my Z10 (yet).
I'm not super technical when it comes to the watts of power used by the Hub but if that's where EVERYTHING is being updated, wouldn't it make sense that it would use a higher than average amount of power?
Just a thought. Cheers.

Does updating multiple apps on my MBP use a lot of battery power?

Tonight my MBP battery % dropped AFTER I updated seven iTunes apps, most being bug fixes. It went from 85% to 73% after the updates were completed. Earlier I was using my Beats Pill with NO drop. I had already put the Beats Pill off by the time I did the updates.
Do updates use THAT much battery power?

Do you mean Mac app store apps? Running Mavericks on a 2011 Macbook Pro should handle it fine, but it can depends on the type and size of the seven apps. It also depends on you wi-fi connection and your screen/keyboard brightness. Wi-fi updates can use a lot of battery because it's time consuming, especially if they're large files.

System Update Repository - Using a lot of disk space

Hi
Looking at the Repository - it seems to be using a lot of space with multiple iterations of similar files
It also appears to be keeping large Setup files as well as the Applications.
Are all these necessary?
Is there anyway to remove them? CAN I delete old files/setup files? (do you need the old version if a new application is present and functioning)
Many thanks

What version of System Update are you running? The bloating of the repositiory was corrected with SU v5, which also redesigned the internals of SU. A side affect is that when V5 is installed, all installation history is lost (from old SU v4). Uninstall your current SU, Reply when YES you see the screen below during uninstall . Install latest SU 5.006.16.

Early 2013 13" MacBook Pro runs slow and uses a lot of RAM, why and what can be done?

Problem description:
My computer is using a lot of RAM. Wondering if there’s a hardware issue, or a software issue, or something else. I currently have no programs open in the Doc, besides EntreCheck. and the RAM is showing about 75% used. I’m looking for suggestions on what I can do to speed it up and make it more functional, and efficient for doing design work. I recently upgraded from the original 4GB RAM (2x2GB), and from the original HD to a 512 GB SSD drive, and upgraded to Yosemite. Perhaps that was too much for this machine? Please help with anything that I can do to make it better! Thanks in advance!
I have a recent back-up, I'm open to saving user files and starting from scratch with the current hardware, etc... but would need some direction on how to do this. I did upgrade myself using Apple provided instructions.
Here are the EntreCheck results:

Here's the new EtreCheck that I just ran. At a glance, it seems I may have missed deleting some things or they are stored in an additional location? I haven't jumped into anything yet to really test if there's a difference in performance for me. Once I do I will post that information.

Safari 2.0.4 - Uses a lot of memory ??

Hello,
I own an Intel iMac MA200.
I noticed after Safari's 2.0.4 update that it uses a lot of memory, sometimes even as much as 200MB
The cure I found is to restart Safari.
Sometimes, I need to even Force Quit it.
When I finish using my iMac, and close the Safari windows but let it keep running (red button), go to sleep, and in the morning check how much memory it takes, it's more then 100MB,
I suspect there is a memory leak with Safari 2.0.4
My OS X version is 10.4.8.
I wonder if there is a known problem with Safari, and if there will be a new update released soon (2.0.5 ?) that will solve this problem, because I didn't have this problem with 2.0.3 .
Thanks in advance,
Idan Mashaal.

Hey !
Thanks for the post!
Sience the Gmail upgrade, Safari stopped being my default browser.
I'm using JCraig's optimized nightly builds for Camino (1.2+)
They seem very memory friendly and Intel Optimized.

I really hope Apple will fix the memory leak and Gmail fix there new interface (the little option button next to the new reply deosn't work - even with WebKit nightly) ASAP - sience SafariBlock and Saft doesn't work well with WebKit Nightly.
I miss my Safari

Under my website data (Settings, Safari, Advanced) there are websites using a lot of data which I have never visited before. Several of these listed sites are for tracking internet usage. Has my phone been compromised? Is there any other explanation?

I have recently discovered a website called bluecava operating on my iphone 4s, according to my website data log. I've never been to this site, but according to my data log this site is using a lot of data, along with other sites which I have never visited before. Does anyone know anything about bluecava (I've done my research, but I'm not finding information about individuals using this to track someone), or have any other explanation for seeing un-visited sites on my data log?
Someone recently mentioned phone "cloning" to me, meaning that my iphone may be accessed remotely. Any information is greatly appreciated!

Thanks a ton! Yeah, I didn't know about any of this until I had reason for legitimate concern. People should be aware of what's available. Someone intent on tracking you won't mind paying bluecava to do it for them...
I'll definitely be updating my browser as well. However, Lawrence, I did find during my research that bluecava DOES NOT operate based on cookies. It uses your IP address to consistently track patterns of behavior, even
within multiple devices of one household, so that deterring the tracking is not as simple as turning off cookies to a site. (See screenshot below from bluecava.com)
If you go to the bluecava site's privacy policy, you can actually opt-out, however, blogs have criticized bluecava for not explaining exactly what happens when a user opts-out. It may be beyond our control...

Mass updates to move lots of positions to one org unit

Hi All,
Can anybody tell me in SAP whether there is a transaction or way to perform mass updates to move lots of positions to one org unit ?
Our users have to perform Re-org changes so they would like to know whether there is a way to move positions at once.

Bharat-
I am assuming that your requirement is to move mass users from One Org node to another. Ex One Plant Org node to Another plant Org node.
If my assumption is correct then, please follow the below steps.
1) Go in to the change mode of Org Plan using T-code PPOMA_BBP
2) Using shift key, select all the users that you need to move.
3) Drag and Drop the selected users to the desired Org node.
If the user IDs are not in sequence then you can use Ctrl key to select the relevant user ID.
Let me know if you have any questions.
If the answer is helpful, please reward points.
Regards,
Upendra.

Seems Firefox is suddenly using a lot of CPU power

My desktop, recently, started sounding like it was really laboring while I wander around the net. And there's a delay as I type messages like this... the letters show up a second or two behind the keystrokes.
I looked at CPU usage (Win XP with all updates) and while I'm doing this, it sometimes peaks to 35% or higher for Firefox.exe.
My laptop has recently started telling me Firefox is using a lot of memory and I should close and restart Firefox. (Also updated Win XP)
It's becoming a big PITA...

It didn't show up when i searched for the problem on Google and it didn't show up when i search here on Firefox's support site either.
And the reason it didn't because it's mostly not about my problem.
'''If' it was one of those things then i would have a high CPU usage the minute i opened my browser, but i don't.'''
'''It will use a lot of CPU power (after a couple of hours) even if i don't do anything '''
And yes hardware acceleration is on and so is submit performance data and i use Ad Block Plus, and there isn't a correctly working theme or add-on out there that could use 50-60% of a 3.2GHz quad core CPU
I don't think this is something that can be fixed that easily

Ditto Using A Lot Of CPU? Fans Run Often

It seems to be the culprit in causing the fans to run fast since installing SL. I stop the process from the Activity Monitor but it starts back. AM shows ditto at 90% when it's running. The fans come on, I stop ditto and they slow down, later the fans come on again, I check and ditto is running again and at 90%...............

Actually resolved this. Related to unzip issue.
Attempting to unzip some files locks up the Archive Utility. Force Quitting the Archive Utility leaves ditto open and using a lot of CPU.
Therefore, I'm using The Unarchiver (as kindly suggested by someone on my unzip problem post) at least until Apple updates the Archive Utility.

Flash player 11.3.300.262 is using a lot of memory

Since updating flash a few days ago the plugin has been using a lot more memory than usual. Normally it uses between 150MB to 200MB, but now i have seen it use up to 900MB.
I've noticed that memory use increases by 5MB or more when navigating through a video until i have to terminate the plugin because of the ridiculous amount of memory used.

Please check if all your plugins are up-to-date. To do this, go to the [http://mozilla.com/plugincheck Mozilla Plugin Check site].
Once you're there, the site will check if all your plugins have the latest versions.
If you see plugins in the list that have a yellow ''Update'' button or a red ''Update now'' button, please update these immediately.
To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Vmtoolsd.exe is using a lot of threads

Hi All,
We're using VMware tools a few years now on our Windows 2012R2 environment.
But the last months we get complains from some of our remote desktop users that our servers are slow, memory is full, and users can't sign out/in.
After investigating this issue, we see that VMtoolsd.exe is using a lot of memory.
And it takes a lot of time to kill the process.
We discovered in the Resource monitor that the process is using a lot of threads (sometimes 80.000). After killing the process the threads are slowly counting down to zero . After that the server is responding normal.
On internet I can't find anyone who has this issue.
We have a lot of servers. This issue is only on a few of them.
We're using ESXi 5.0 and VMtools 8.6.11 build-1310128
Does anyone know what is going on?

Wow, it looks like you're using the tools that came with ESXi 5.0 Update 3 from October 2013. There have been several patches for ESXi 5.0 since Update 3. The most recent patch for ESXi 5.0 has newer tools (8.6.15 build-2495133).
See here: http://packages.vmware.com/tools/esx/5.0latest/index.html

IPhone data lost during update using friend's pc.

Hello
My g/f has an iPhone 3G which she has used a lot for 18 months and had lots of saved texts and photo’s etc, but she is not very good at backups and has lost everything when upgrading from the original software, (about 2.6) to the current 4 something. Very unfortunately and unwisely, this was not even done on her own computer, but on a friend’s.
She has her own desktop pc and uses iTunes but hardly ever connects the phone and always declines to update when she does connect. She last connected about 6 months ago.
On New Years Eve we were at a friend’s house and a knowledgeable sounding guest offered to update her phone on her friend’s computer. They have their own iTunes account on it.
We connected the phone up and it started updating via the iTunes program and after one or two hours the software and firmware update completed. The sync options were then presented and as the knowledgeable person had by then gone home we thought “Well, we don’t want to sync with anything on this computer, we will disconnect and sync later on g/f’s home computer.” (We are still not quite sure what syncing is although g/f thinks she has synced before from home)
As you have guessed, the software upgraded fine but phone has been wiped of all data, pics, iTunes downloaded, texts, contacts, notes, calendars.
The obvious problem in this case is that we used someone else’s pc. I have located the mobilesync backup folder on g/f’s own pc and it is empty.
Is there any hope that we can retrieve anything from our friend’s pc which we updated on? Would a folder have been created separately on their pc for my g/f’s phone?
I was not watching the pc the whole time it was updating and did not see everything that happened, but what I have established is that when I plugged her phone to her pc yesterday I got the warning message saying that the phone has been synced to another computer, (presumably the friend’s) and all data on the phone will be erased if I sync on this one (her one).
What I don’t know is whether this warning message had come up on New Years Eve on the friend’s computer while updating, and whether it was ignored.
We have been back to our friends but they are getting a bit fed up with us, I think they will put up with us using their pc one more time so this time we will have to know what we are doing. I have an external HD so I could maybe copy the iTune files from their pc and work on them from home later?
With thanks

Well.... I guess based on the replies, I should consider that password manager info not being part of the backup is normal for all of us.
If not, maybe it's just one of these numerous glitches and bugs I have since I own a blackberry.

The reason your applications do not work in Lion/Mountain Lion is that they were written for the older PowerPC CPU that all Macs used up to 2006. When Apple made its transition to the Intel CPU, they licensed software that they included in all versions of OS X (from Tiger to Leopard and optionally, Snow Leopard) called Rosetta.
Rosetta miraculously allows PowerPC applications to work on the Intel processor transparently; you do not know it is even present.
The problem is that after 6 years of the transition, Apple's license to use the underlying software expired for OS X Lion and all version thereafter (and it is doubtful that the current owner of the software, IBM, would relicense it, even if Apple were inclined to do so).
So you do not have to accept recriminations from others for previously using Rosetta without even knowing it was present and running!
So for those of use that need to upgrade to Lion/Mountain Lion, I have offered the option to install Snow Leopard (with Rosetta) into Parallels 7:

And now Mountain Lion:
If you are unable or unwilling to update your inventory of PowerPC software, this solution offers you an alternative for not more than the $29 cost of Snow Leopard and $79 cost of Parallels (cheaper via internet sources).
Full Snow Leopard installation instructions into Parallels 7 are here:

Why is firefox 7b using a lot more memory and cpu on my computer?

I'm trying firefox 7 beta in a debian squeeze box. It is using a lot of RAM and CPU compared to previous releases of firefox(I've tried disabling all plugins and add-ons, not a big improvement). In the follow link here is a summary from about:memory, websites tabs opened at that time and the usage of % mem and cpu of my system: http://pastebin.com/8ji1gmLk
I'm using firefox on all my computers for a while now. So changing the browser is not an option for me now.
It did crash few times when loading a lot of tabs. Please let me know if there is another information that would be useful for fixing this. Thanks

Is it using a significant amount more resources than 6.0 did?
I noticed 6.0 is a VAST resource hog over 5.0 and earlier. It's a very bad flaw in the new version, and has a lot of people upset.
What has me curious is whether this is a new resource problem or whether it was present in 6.0 and you are just not noticing it.
One suggestion: Don't run BETA versions of ANY software on "all your machines". Not when rolling back the version is not an option. That's generally a bad idea, since beta versions are likely to have bugs.
With FF, now, I would never let it automatically update. I don't trust their new update policies, so I would suggest you turn "auto updates" to OFF, and do it manually, only after you hear the new release is stable, which we know 6.0 is NOT.

Do OS X updates use a lot of power?
