Software :: Grapher.app Use Wrong Name?
Apr 1, 2008
I was just wondering if anybody else noticed that the examples in Grapher.app use the wrong name for one of them. They have the Lorenz Attractor, only they call it the "Lorentz's Attractor." They credit Hendrik Lorentz, the dutch physicist known for his work in electromagnetism and [now] for his transformations used in Special Relativity. The Lorenz Attractor was done by Edward Norton Lorenz, the meteorologist who accidentally discovered chaos theory.

I saw an article on grapher that mentioned it was part of OSX 10.4. I'm running OSX 10.5.6 and can't find grapher. Where is it?

I'm trying to find out how to use the application "Grapher", but I find it difficult! It's easy for me to draw the graph by telling the program which equation I want it to draw, but I don't know how to and whether it is possible to draw something manually in the graph, for example the slope.

Does anyone use grapher? I have never been able to figure out if there is in fact a way to turn on the axis labels x,y,z and possibly get some values on the axes as well. Anyone ever been able to do this?

I have my MacBook set up for dual monitors. When it boots up, it boots on the actual Mac screen, not the external monitor. How can I change this?

I've got a wired problem. I have MacJournal (from the recent MacHeist bundle), and whenever I type "MacJou..." into the Spotlight search box, MacJournal turns up with it's icon and three (asian looking) letters/signs next to it. Sure enough, the application's name in Finder is "MacJournal", and it's english when I launch it. I have English as main language in System Preferences.
Not really preventing me from doing anything with it, but it's strange. And who likes strange things on her/his computer? So: what can I do?

When I place jpeg images on a USB flashdrive and give them to students using PC's in my Photoshop Classes. There is a second set of files everytime which begin with ._ (dot underscore). They are some kind of false file but are confusing to new students. If they scroll down below these files they will find the real jpegs.

I have my Mac Pro set up to boot at a certain time every morning using the energy saver schedule feature. I have also set a disk I've named "Lion HD" as my startup disk. I also have a disk named "Lion HD back up" which is an exact bootable clone created with "super duper". Every now & then the computer boots into the Lion backup rather than the Lion HD. Any ideas why this happens & what I can do to fix it?

Mac Pro, Mac OS X (10.7.4), 8 gig, 30" cinema

I updated a Mac G5 desktop from 10.5.2 to 10.5.8. When I finished I realized I had used the server version of the combo updater instead of the regular one. The machine seems to be running OK. Will this cause problems and how should I fix it.

I wanted to force quit an application on my first gen MacBook running Mac OS X 10.6.3, so I looked up the short cut key command from the Apple menu. I saw that it was option-command-power-button. I pressed these keys, and my Mac instantly displayed a black screen. After about five seconds, my Mac made the usual sounds of starting up. I booted up, and nothing seemed to have been affected, so I double checked Console, which didn't help much. I looked up the short cut key command for force quit online. The Internet says its option-command-esc. I tried the command, and up popped the force quit prompt. So why is the short cut key command WRONG on my Apple menu?

I'm using a 1 Gb pen drive, and I've just noticed that I can't even change a file's name because the system says something like "the operation cannot be completed because the disk "x" is full. Delete some files and try again" (please note that my system is in Spanish and the translation might differ).
The point is that I can see "85 MB available" in the status bar... Some files I can change them, some others I can't... I can copy some files and some others I cannot... What's going on here?

So my teacher's iMac is behaving weirdly. She turns it on and she is asked to type in the password to log in. It's not set as automatic login. But it says the password is incorrect. She is positive the password is typed in correctly. She reboots it and types in the same password. This time, it lets her in. I tried repairing permissions but to no avail.

Whenever turning on my computer, my webclip shifts to an area it's not supposed to be. It doesn't do this as long as it's on, even when I go out and into Dashboard. What I do:
1) Safari > Preferences > Advanced > "Check Never use font sizes smaller than (28)"
2) File > Open in Dashboard
3) Edit to smallest size
4) Safari > Preferences > Advanced > Uncheck "Never use font sizes smaller than (28)"
Should it be of any help:[URL:...]

According to the screenshot, both Users (green) and System (red) uses 0,19% CPU each. Which means that idle (black) should be around 99%, which it clearly isn't. If I check each process individually, none is using more than 1% of CPU. The screenshot is taken after a reboot and I don't use and third-party background services like VMWare. It's Mac Pro 2.66 Quad (2009).

So I tried to set up bootcamp on my 10.5.6 17" iMac. the windows installation failed because of a bad disc so I restored my computer using my OS X disc and time machine. Now my display in OS X is being forced to 1024x768 and I cannot change it to anything else. It looks terrible and there are some artifacts... Any idea what the heck happened?

I usually leave my iMac turned on with just the monitor switched off. That was also the case when I left yesterday for a day trip. Coming back today, I noticed that it was shutdown. Pressing the power button, I can hear the familiar "ding" of boot up, the fans running, the usual dvd drive sound and after that it just shuts down. Not even the monitor will power on. Before I start panicking since various thoughts are crossing my mind, is there anything that I can try to possible identify what's wrong?

After trying to customize my icons with LiteIcon and CandyBar and everything, my dock refuses to show up, at all. When I go to Finder and then to Dock, it has the beach ball.
When I try to go to the Applications folder, it has the beach ball.
I've tried Terminal "killall Dock" but it doesn't appear to be a Dock problem, but rather an Application problem. Maybe even both.
This is my first week using a mac, I don't know what to do. I'm currently repairing disk permissions?

I had correspondence in recent months with a perfectly normal chap called John Hoekstra. I have recently noticed that his name is appearing as me in my mail. For example in the panel above a mail it will say FROM: John Hoekstra instead of me, and I happen to be another John, John WicXXXXXX, confusing recipients more!
Something like:

I'm running a macbook pro (2.4ghz intel core 2 duo). I had bought snow leopard however my nvidia graphic card gave out and I had to take it for repair. Long story short when the repairs were done they had replaced it with a 2.2 ghz intel core 2 duo with 128mb of video ram for the 8600gt rather then 256mb. Being the very anxious person I am, I want to know if I can upgrade my computer with the wrong motherboard to snow leopard now or if I should wait to get my motherboard swapped and would there be any difference in the performance if I was to do it with my 2.2ghz rather then my 2.4 ghz.
I am running OSX 10.4.11 currently btw

Suddenly having problems with sending emails via Mail for Mac. Some, but not all, messages show in the display window as having been sent to the wrong recipient.However, when you click on them, the details shown are correct and they seem to be getting through to the intended address. So it's a display issue of some sort rather than Mail actually sending to the wrong place.Can't find any reference to this issue in Mail Help or online forums.I'm running OSX 10.4.11, Mail 2.1.3.

Just a strange occurrence this evening: I just watched a DVD on superdrive: when it finished, I ejected it and glanced at my Finder menu bar. IStat Menus gave me a temp of 135 and rising (went as high as 140 degrees a few minutes after ejecting and shutting down DVD Player). But the fans aren't on at all--never came on, as far as I can tell--and the MBA feels cool to the touch. Now it's maybe 20 minutes later and iStat reads temps as still at 115 degrees. But my laptop feels totally cool to the touch. I restarted, hoping to reset iStat, but no change. Any idea as to what's going on?
