Adjust Mac OS X display brightness from the Terminal - Matt [Danger] - 0 views

  •  
    One of the classrooms I maintain is comprised of 2.4Ghz iMacs (MB323LL/A) that are dual booted with Windows XP and Mac OS X. Sometimes when the workstations are restarted from XP to OS X the display brightness gets changed to its dim power saver setting. This requires the user manually increase the display brightness by pressing the F2 key, which is inconvenient. I haven't been able to determine the cause of this issue so I wanted to create a login hook to increases the brightness as a temporary fix. OS X doesn't ship with a command line utility that let's you change display brightness. Fortunately, Nicholas Riley has written a utility that uses OS X frameworks to accomplish this quickly and easily. Here's the code

XBinary: Extended Binary Format Support for Mac OS X - 0 views

  • Extended Binary Format Support
  • © Amit Singh
  • January 2009
  • ...51 more annotations...
  • —With the advent of x86-based Macintosh computers, Universal binaries, originally known as "fat" or multiple-architecture binaries, appeared in Mac OS X.
  • Universal Binaries
  • for one or more architectures
  • along with a header that describes each constituent binary.
  • a wrapper that contains Mach-O binaries
  • a "4-way fat" executable could consist of Mach-O executables for the i386 (32-bit Intel), x86_64 (64-bit Intel), ppc (32-bit PowerPC), and ppc64 (64-bit PowerPC) architectures
  • Mac OS X does not provide any kernel-level or user-level interfaces to extend binary format support.
  • we'll need to write special software
  • new kernel functionality
  • software will involve a kernel extension.
  • extend the kernel
  • and execute them through specified handler programs.
  • Let us call the new software that implements these features XBinary. binfmt_misc Those familiar with the Linux kernel will realize that functionality similar to what's been described here exists in Linux as the binfmt_misc kernel feature. XBinary is conceptually similar
  • XBinary also has some Mac OS X specific features.
  • download and install the XBinary package
  • a command-line tool (xbinary
  • a kernel extension (xbinary.kext)
  • research software at this point
  • choosing the best library from an extended fat library file.
  • for developers, researchers, and power users
  • take XBinary for a spin
  • XBinary: extended binary format support for Mac OS X Copyright (c) 2009 Amit Singh. All Rights Reserved. http://osxbook.com The XBinary software allows you to extend the Mac OS X kernel such that it can recognize arbitrary binary formats and execute them through specified handler programs. (Mac OS X natively supports executing only Mach-O binaries, Universal (fat) binaries, and interpreter scripts.) XBinary consists of a kernel extension (xbinary.kext) and this command-line tool, which lets you control the XBinary facility. This requires superuser privileges, so you should run this tool using sudo(8). The XBinary kext must be loaded for the facility to be available.
  • You can add and manipulate in-kernel entries that enable recognition of binary formats.
  • You can also specify flags that affect how a matched entry is processed. By default, the argument vector IS adjusted and setuid/setgid binaries are NOT allowed.
  • make experimentation involving new binary formats easy
  • Let us look at Java applications
  • then specify this wrapper script as the interpreter
  • and subsequently invoke the Java application launcher.
  • given a Java class file
  • a wrapper script
  • We don't even have to write such scripts

      :-)
  • a Universal binary containing, say, Tiger and Leopard versions
  • simplify code creation and maintenance.
  • Consider a 2-way fat binary containing i386 and x86_64 architectures.
  • operating system versions in addition to processor architectures.
    • Graham Perrin
       
      :-)
  • Now think of an "extended" fat binary mechanism that incorporates
  • our hypothetical extended fat binary contains eight "architectures"
  • the extended fat feature as implemented by XBinary is not a complete implementation
  • These examples assume that you are on an x86 (little-endian) machine.
  • XBinary requires Mac OS X 10.5.x (Leopard).
  • Executive Summary This document discusses XBinary, a new software that lets you add kernel-level support for executing files in arbitrary binary formats on Mac OS X.
  • Extending Executability
  • recognize arbitrary binary formats
  • using the xbinary tool
  • copious "help" output
  • Each entry must have as its name a unique identifier string up to 31 bytes in size. Additionally, a set of other arguments specify to the kernel how to recognize that binary format and which interpreter to invoke to handle it. XBinary can recognize a binary EITHER by matching magic bytes within the first page of the file OR by matching a file extension. OTHER_ARGS must be a valid combination of the following arguments (some are optional).
  • that will determine the startup class name
  • Bonus Feature: Extra Fat Binaries
  • Since XBinary is experimental, why not experiment with such a feature too?
  • XBinary wouldn't be able to help the dynamic linker

Mac File Recovery In Case Of Desktop Database Corruption - 0 views

  •  
    In Mac OS X, the Desktop Database (Desktop DB) is a collection of invisible files, which store the location information of all the files on your Mac OS X hard drive. Because this database contains the location of all the files on hard drive, if it gets damaged or its size grows too large, many issues might take place. In such cases, whenever you try to access a file or start an application, the process halts with an error message stating that the desktop database is corrupt and you need to rebuild it or delete and recreate it. In such situations, you can not access your mission critical data from Mac OS X hard drive and come across serious data loss situations. In order to sort out these data loss circumstances, you need to opt for Mac File Recovery using using appropriate methods.

Multi-Safari - 0 views

  •  
    Safari normally use the Web Kit framework found inside Mac OS X to render web pages and execute javascript. This means that if you preserve an old version of Safari to run it on a newer version of Mac OS, it will use the newer Web Kit found in the system and you will get the same results as with the newer version. Thus, you would normally need a separate installation of Mac OS X for each version of Safari you want to test a website into.

Mac OS X market share cracks 8% (computerworld) - 0 views

  •  
    Apple Inc.'s Mac OS X market share has passed the 8% mark for the first time, a research company reported today. In September, Apple's operating system ran on 8.2% of the computers that accessed the 40,000 sites monitored by Net Applications for clients, the company's data showed. The Mac's share of the operating system market was up over August's by nearly four-tenths of a percentage point, the biggest one-month gain since May. Apple tends to post significant increases in September, according to Net Applications. Last year, for example, Mac OS X climbed by 0.45 points that month

Customizing the Finder sidebar in OS X | OS X Help - 0 views

  •  
    Every window you open in the Finder of OS X has what is called a "sidebar" attached to it. The sidebar is nothing more than a quick way to get to places you often visit. Apple has been kind enough to seed it with some common items. These default items may or may not be useful to you personally. The good news is, you are free to change the sidebar to your liking. You can even close off the sidebar and make it disappear if you are so inclined.

CreativeTechs Tips: Set default applications in Mac OS X. - 0 views

  •  
    RCDefaultApp is a free utility that CreativeTechs has started adding to our recommended Mac OS X installs. It adds a special preference pane that allows you to quickly change the default application for many common situations: * Open all your .pdf files in Acrobat instead of Preview. * Pick a different default mail client or web browser. * Control what opens when digital cameras or webcams are plugged in. * Close security holes with how certain weblinks are handled. Of course you can change these settings other ways. But RCDefaultApp makes it much easier by putting the most requested controls into one location - a new "Default Apps" option at the bottom of your Mac OS X System Preferences.

Mac OS X 10.5.7: User cannot log in on managed client - 0 views

  •  
    After updating to Mac OS X 10.5.7, a user may not be able to log in to a managed client workstation. On startup, or after entering the user name and password, the user may be prompted for an administrator name and password, but nothing can be entered. This issue can occur on PowerPC-based Macs if the file /etc/authorization is not updated correctly when installing the Mac OS X 10.5.7 Update.

10.5: Disable printer queue password requirements - Mac OS X Hints - 5 views

  •  
    Mac OS X 10.5 requires you to enter an administrator's password to pause/resume a print queue, where no previous version of OS X has done so. This is extremely annoying in a lab setting -- if there's a paper jam or something, the queues on all the computers need to be restarted by an administrator, instead of the user just clicking Resume. I haven't seen a solution to this elsewhere, so here's what I came up with:
