Rpcsvchost

Have you installed Trusteer Rapport for online banking? I've had lots of problems of overheating and high fan speeds in the past which turned out to be due to this.

I've just had the same problem as you and followed Linc Davis's suggestion and it was Rapport that was causing my problem despite the fact that it was set to be inactive in preferences.

I complained to my bank about the problem in the past because their system prompts me to download it every time I log on. The bank IT chap told me they are aware that some Macs have problems with it and to tick the option that I am on a network which does not allow me to download it. This has the effect of stopping me being prompted for a month.

Yeap, emptying the trash did it for me as well.

When you have the problem, note the exact time: hour, minute, second.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.

Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.

Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

I have this same problem, CPU is 95% to 100% used for rpcsvhost, the reoccurring line during my +87 degrees C is:

com.apple.launchd.peruser.501[1023]: (com.lexmark.bmlaunchd) Throttling respawn: Will start in 10 seconds

Does anyone know what I can do to remedy this reoccurring problem?

Not sure if I should have started a new thread or not, but I'm having the same problem. I have an early 2011 MBP 2.3 i7 with 8 gbs of ram. I recently did a clean install of Yosemite and installed Logic Pro and Mainstage 3. (Nothing else on this machine. It is for music only)

After completing the install, I noticed that simply opening Mainstage put a 40-50% hit on CPU. And playing for any amount of time with just a single internal instrument would result in spikes well over 100% and eventually it would stay that high. The result is an extremely hot and noisy machine. I ended up doing another install of Yosemite, and now when I boot, rpcsvchost spikes at 100% before I launch any program.

After reading this thread, I re-booted and found this in the logs:

Any help understanding what this all means would be greatly appreciated!

Dear Linc Davis,

I have the same issue as described above.

What are we looking for? What would be the important parts to analyse?

My MacBook Pro early 2011, 2,7 GHz i7, 16GB RAM uses 100%+ of CPU on rpcsvchost right from startup, no other programmes running.

I have the same issue on an older (2007) iMac: rpcsvhost uses almost all resources right from boot up, with no other programs running. The old machine is much slower since Mavericks upgrade, and frequently is completely unresponsive for long periods.

Hi, I had the same problem today after a long sleep and installing of Yosemite I got this behaviour. What I did feels kind of random but that was it for me. I emptied my trashcan (which hade over 1000 of items in it), and while it was deleting the CPU usage kept declining until it was ready, and now... aah silence, no rpcsvchost running at 95-100%, everything is just idling. Could be worth trying for some that visit this thread atleast.

In my macbook pro the problem was faulty hdd ribbon cable causing 100% cpu usage of rpcsvchost process.

Just unplug the connector from logic board and boot your mac os X from external drive and check cpu % in activity monitor

I have just upgraded my mid 2009 macbook pro with 8gb of RAM and swapped the Harddrive for a crucial 250gb SSD. I make a bootable OS X yosemite to reinstall on the computer. After starting the computer the fan was running really loud and found that I have the same problem with rpcsvhost using 99%. I have opened console and this is part of the logs I am getting

Can anyone help me solve this problem? I would really appreciate your help.

This occurred as soon as my 16GB Early 2011 MacBook Pro launched OSX Sierra 10.12.1 after I'd upgraded my internal SSD from a 500GB Samsung 840 Evo to a 1TB Samsung 850 Pro that had be "replicated" using SuperDuper! Fortunately Rpcsvchost went down from 99% CPU usage (with my MBP's internal fans running at full "leaf blower" speed (6,200 rpm) for about 5 minutes... Then Rpcsvchost stopped running and my MBP returned to normal operation.

I'm thinking it was related to the installation of my new SSD since DropBox also went crazy right after the SSD replacement running at 115% CPU (Yes that happens when you have 4 dual core processors = 8 virtual processors).
