Java kills my Safari and slows computer

Everytime I run into Java (script or applet) while surfing on Safari it takes forever to load (at least 3-4 minutes) then slows down every other application until I quit Safari (i.e. copying and pasting in Word takes 5x as long if Safari is running in the background-but only after loading Java). I have all my Safari and Java updates installed. I have emptied my cache, cleared my history, trashed my safari icons folder and set it to read only, I've turned off all my auto-fill preferences, and I even trashed and reinstalled Safari, preferences and all. I have always had issues with Safari and Java, but things seem to be worse since I upgraded to Tiger. Only have this problem on my Powerbook, my G4 tower (which is 3 years older) has no problem loading or running Java, even after the Tiger upgrade. I thought it might be a memory thing, so I ran a hardware test, but everything passed. Any thoughts?

Nevermind. I found my answer! I just cleared my Java cache (duh!) If anyone else has a similar problem go to: Applications>Utilities>Java> and open your plug-in settings, click the cache tab and click clear. Worked like a charm. Java loads instantly now, and no slowing down other apps either!! Woo-Hoo! I unchecked "enable caching" to keep it from happening again, of course you can limit your cache size too.

I just downloaded the new Java update now Safari is slow and I'm getting the spinning beach ball of death.

Typing in Safari with the new Java update that I downloded today causes the spinning beach ball and slow loading of pages. As usual, Java is causing problems. Just once I would like to see things run without having to depend on Java.

24Golfer:
I think there's something more, because it keeps happening to me with the Finder where it says that it is not responding when I go to the Force Quit window.
Are you saying that the Finder is reported as not responding? If yes, try this:
Go to Home > Library > Preferences > com.apple.finder.plist
Drag com.apple.finder.plist to desktop
Restart computer.
Monitor to see if anything changes, or Finder is still not responding.
Good luck.

Aging and slowing computer, time to replace RAM?

I have a late 2008 Black MacBook with 4gb 667MHz DDR2 SDRAM and about 45gb (of 250gb) of free space on my HD. Lately, my poor MacBook has been getting extremely slow even with the most mundane of tasks like checking my email. I notice that my memory usage fluxuates a lot more and the computer gets significantly hotter lately than it did in the past, so I'm thinking that the problem is related mostly to that more than anything else. What I'm trying to figure out is whether replacing the RAM would solve this problem, or if this problem may be related to something else. Please let me know your thoughts, or if other diagnostic material is needed to help further troubleshoot.

If the computer is working, then the RAM is fine. RAM doesn't slow down with age. You have other problems - maybe not enough RAM.
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion/Mountain Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Java update crashes Safari and Mail

When upgrading to the latest version of Java, I got a message at the end of the cycle saying that the "source media" was corrupt (or a similar word). I now find that both Safari and Mail crash immediately upon trying to open a URL or a mail message.
Do I uninstall Java? If so, is there guidance on the process? Where might I get the latest safe version of Java? Is Java the source of the Mail problem as well?
(Needless to say, it pays to fear updates.)
Thanks,
Tim

I have a similar problem after the Java 6 update failed to install through software updater.
I get a crash when trying to load Safari and a few other programs.
I tried downloading the Java update separately and installing it, but I get the same error "Source file is corrupt". I've tried repairing permissions and a disc repair, but despite these working OK I'm still encountering the same problem.
I'm now thinking of rolling back in Time Machine, but fear that this will happen again when next updating.
I can attach an error report if necessary.

Safari and Youtube + Computer lagging [after yosemite update]

Hello all,
Lately, when I go on youtube.com (with safari as my default browser), there is an extreme amount of lagging. Youtube takes forever to load, and after refreshing the page a few times, the pace of the site is still very slow. When I click a video, I usually have to cancel the tab and start over or click the video several times before it actually loads. After that, I get the video and the comment section says "loading..." and never loads! Does anyone else have this lagging issue?
Not only youtube, but my computer has started to lag a bit? my tablet doesn't function that well with my computer (even after updating the driver/reinstalling twice). Also, and of the safari tabs I eventually have open all end up lagging, and I have to restart my computer constantly. Does anyone have a solution for this?
Oh, I'm using a Macbook air.

Hey OrangeSlices,
Thanks for the question. After reviewing your post, it sounds like Safari is running slowly. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.
Safari 5.0.1 or later: Slow or partial webpage loading, or webpage cannot be found - Apple Support
Thanks for using Apple Support Communities.
Have a nice day,

Macbook Pro 2011 loud fans and slow computer functioning?

Today my Macbook has suddenly begun to act slow and the fans are running quite loud. I read online that I should try checking the activity moniter, and I did this, and a program is currently taking a large portion of my CPU. However, I am unable to quit it and I'm sure it is the problem. In one of the description fields it is lableled "root" and says "kernel_task". Someone please help me out!

Actually I'm still running snow leopard. But this problem is confusing me so badly. I have tried several times to totally restart the computer by holding down the power button for a few seconds. The MacBook restarts fine but upon startup the fans start running loud again and the Performance of the computer is clearly slower than normal. For example, when I maneuver with the trackpad down to the dock the icons are very slow to respond. Also, normally upon startup my keyboard illuminates upon viewing the log in screen, however for some reason this is not happening either.
I hope someone on here has the solution to this it would be greatly appreciated.

i am having grave difficulty using thompson learning, because it does not support the common os x browsers, and netscape does not recognise the jre 1.5 that i have installed. can apple provide some serious update to safari, or could someone advice me as to how to proceed in making netscape install the jre1.5 plugin

I'm having the same problem with wallstreet institute, an error occurs saying "Client browswe unable to communicate with server - missing Java Virtual Machine (JVM). You will need Sun Java Virtual Machine". Please contact administrator."
No helpful idea from gravis store or apple phone helpline.
Any idea?

Update to 7.1 causes screen freeze upon closing from Safari and slow wifi connection.

I updated my iPad 3 last weekend. Right after the update the screen froze and I had to restart it by holding the home button and on/off switch. Ever since then the screen freezes a minimum of once a day. This normally happens when closing Safari. I've also been kicked off of Facebook several times and brought back to the home screen. Not to mention my wifi internet connection is running super slow at home and work. Any ideas of what this is happening? My husband updated his iPad 2 and is not experiencing these issues. We think the update may have been corrupted but not sure what to do. Thanks in advance for help on this.

The screen froze again yesterday. This time it happened while I was in the photos app. The screen starts to shrink when I pinch it but it doesn't close all the way. I get a small "thumbnail" of the screen which gets stuck. I am very good about making sure I don't have a lot of open apps, I try to close them all everyday by double clicking the home button and swiping them up. If you have any ideas please let me know. I am going to try and keep a log of when this happens, what is open in the background and which app gets frozen. Thanks again for the help on the internet slowness. It is working fine now. Not sure if this makes a difference but this is a refurbished iPad 3 that is about a year and a half old.

Why is the Java runtime resource hungry and slow?

Hi,
First of all let me make it clear that I'm not here to bash Java. I'm a big fan of the technology. In fact I believe in its potential as it is the only true 100% cross-platform runtime. Now that it has been open sourced, it has just made me happier,
However, the only factor which has been hurting me is that the Java runtime is resource hungry and has long startup times.
Consider a Adobe Flash .swf file with lot of animation, it is opened by the Flash player in a snap. On the other hand Java applets (with same amount of graphics) take several seconds to load even from the local machine and also require much more memory. With the introduction of Flex flash might become a platform of choice for RIA. Java FX has made matters worse. The loading time of Java FX is much higher than that applets themselves.
The problem with Flash Player is it not 100% platform independent. For example the latest version of player was released for Linux several months after it was released for Windows and Mac OS X.
Is there any way to make the Java runtime use less memory and start faster? If this can be achieved I feel that applets are a better choice over Flex for building RIAs. After all appearance is not everything and definitely Java is a much more robust platform than Flash.

I'm running it on Kubuntu Linux. Even on this Flash Player is much faster at loading embedded Flash animations than JRE loads applets.
Seriously, if alone the speed of loading applets can be increased, the world will have an extremely robust platform for RIAs.

IMac mail is frozen and slows computer, occasional screen flicker.

Anybody got a fix for frozen mail? It seems to slow down the machine and I've also noticed a flicker/buzz style jump to the screen occasionally and thinking it is related.

iMacs are not designed to have the graphics cards upgraded. If your old card is bad and you feel competent to exchange it for the same one that's really your only GPU option. Apple never said the iMac GPU's were upgradeable and frankly I've never heard of anyone successfully upgrading an iMac GPU.
As far as the adaptor well you could bring your system into an Apple Store and have it checked out by a Genius, it's a free service. I don't know how to make a reservation in Japan but I'm sure you can from the Japanese Apple site. The link in the US is:

Safari and Java Problem

Hi,
I'm having a problem with the newest updates to Safari. This problem did not occur until late december when I installed several updates via Software Update.
Problem:
I use a photo uploader on a website from my company (unfortunately I can't give out the URL, as it is protected). But it is similar to many other photo uploader sites - load a Java applet, drag images files into a Java window, the files are added to a upload list and then uploaded.
Now, if I drag 10 items into the window, only one or two will be added to the list. If I drag them in one at a time, all the images will be added. Previously it was possible to drag as many as one wanted in.
Now the really irritating part : During the upload, the Java uploader completely hijacks Safari. The window the uploader allways stays active on top. If I open a new tab or window the uploader window will reappear on top and dominate the action. The only way to get anything done while I am uploading photos is to open another browser like Firefox. Safari is completely occupied with the Java program.
Computer: MBP 2.16 GHz, 2GB RAM, OSX 10.4.11
Safari 3.0.4
Java 5.0 (not sure of the revision, but it is the most recent)
Any help would be greatly appreciated.

I had similar Java problems with Safari and Firefox. I downloaded Navigator and now can run any Java app I need. One thing that may or may not have had any impact: when installing Nav, it asked if I wanted to import settings from Safari or Firefox. I chose not to import any settings. Works perfectly.

Safari VERY slow -- any ideas?

Help! Safari has basically ground to a halt loading web pages on my G4 running Tiger 10.4.3, and/or I get weird error messages. I've tried lots of things suggested on boards -- fixing disc permissions, Unix repair function fsck, running MacJanitor and Onyx, dumping preference files, emptying caches and the icons folder, removing duplicate fonts, etc. -- but the problem persists. Any new ideas? It's driving me crazy! Many thanks.

Hi:
Since writing my first post, I came across this page, which discusses the memory-hog aspects of Safari and slowness when multiple windows/tabs are open. This also led me to Privoxy which kills two birds with one stone. Privoxy enables a local proxy server that blocks a fair proportion of banner ads, especially those with Java animation. After installing the package, network settings must be altered to use a manual proxy server for http and https protocols: the server address is 127.0.0.1 on port 8118. So far it has worked well for me, improving speed when I have a lot of tabs open and blocking annoying ads as well.

Time machine slows computer

When TM does its hourly thing the computer slows dramatically for abut 5 minutes. Is it supposed to?
If this is correct, is there a way I can ask TM to forget the hourly back up and do a daily only?
Geoff

on an older and slower computer like yours (your profile indicates 1GHz iMac G4) this will happen, yes. I had this problem with my powerbook. Try [TimeMachineEditor|http://timesoftware.free.fr/timemachineeditor> to change the backup intervals.
