The group for pre-Intel Mac users who still actively use Mac OS 9.2.2-bound hardware and software. Users of Adobe Pagemaker 6.5, Nikon Slide Scanner v3, peripherals and software with scsi. 'ALIVE OS® is an opportunity to travel inward which is so important because that's really where transformation happens. Although I'm not new to a lot of the things that were introduced through this course, It was explained to me in ways that I could really relate to and do the work through the exercises and interaction in my small group to. The story of Dead or Alive 6 MacBook OS X Version begins after a strange incident in a village. Kasumi who is a successor of the legendary Mugen Tenshin ninja clan decided to leave her clan and become a runaway ninja. Also she is living now in a secret hermitage in a mountain village. Elive is a non-commercial, cost-free operating system made for the daily use; a much faster, friendlier, and feature-rich replacement of your high cost and ineffective default OS. Turn that up to 15-year-old equipment into a high-performance machine with a dazzling interface.
PearPC is an architecture-independent PowerPC platform emulator capable of running many PowerPC operating systems, including pre-Intel versions of Mac OS X,[1]Darwin and Linux. It is released under the terms of the GNU General Public License (GPL). It can be executed on Microsoft Windows, Linux, FreeBSD and other systems based on POSIX-X11. The first official release was made on May 10, 2004.[citation needed]
The emulator features a just-in-time (JIT) processor emulation core which dynamically translates PPC code into x86 code, caching the results. Despite running only on x86 host architectures, the JIT emulation core runs at least 10 times as fast as the architecture-independent generic processor emulation core. However, according to the man pages supplied with Debian's packages of PearPC, even the JIT core runs around 40 times slower than the host machine would if executing native code.[citation needed]
Until December 2005 PearPC advanced quickly in speed, stability and features. After that time, however, there was no new release until July 2011 - five and a half years later. Individuals had also been working on builds with more features such as native CD-ROM support and even progress in emulating sound had begun.[citation needed] Builds including AltiVec emulation to run applications that require a PowerPC G4 processor were also produced, although there were numerous problems (mainly interface glitches) with running Mac OS X Tiger using such builds which were not resolved. Support for graphics acceleration was also worked on, which in theory should provide a major performance boost due to OS X's hardware-accelerated GUI known as Quartz Extreme which is currently not supported in PearPC.[citation needed]
Shortcomings[edit]
The current official version of PearPC is 0.5.0 (released July 12, 2015). While its PowerPC emulation handles most applications and the emulator already has an impressive feature set, the project still lacks features needed for a complete emulation of the PowerPC experience:
- Sound emulation (there are PearPC sound-test builds on the web, usually called ppc-snd)
- G5 (64-bit PowerPC) emulation
- Apple Disk Image (.dmg) support for use as an image (currently, to use a .dmg image the file must be converted into an ISO image (.iso)
- Mac OS X Leopard support (instead, try using OSx86)[citation needed]
On June 6, 2005, Apple's (then) CEO, Steve Jobs, announced that Apple would begin switching their computers' architectures from IBM's PowerPC to Intel's x86 platform. The transition was completed in August 2006. The news raised a lot of questions about the future of the PearPC project, because although the project itself is a PowerPC emulator, it is used primarily to run Mac OS X on x86 machines. As Mac OS X can now be run natively on the x86 platform, including on non-Apple computers (albeit in contravention of the Mac OS X license agreement), interest in PearPC has waned since and attention now largely centers on running Mac OS X natively on x86 hardware or in virtualization software such as VMware Workstation.[citation needed]
Frontends[edit]
PearPC currently lacks its own GUI — the 'Change CD' button found in early versions has been eliminated because it rarely functioned correctly. However, developers have made frontends for the program. Two of these are PearGUI, which looks like a Mac OS X application but is incompatible with current versions of PearPC, and PearPCCP (short for 'PearPC Control Panel'), which is compatible with PearPC 0.3 and newer. PearGUI's incompleteness annoys many users and its 'Create Disk Image' feature is not yet complete (a severe shortcoming), but many users have praised its GUI. PearPCCP has a built-in configuration wizard in addition to other advanced features, but is hindered by what many users believe to be an inferior interface and several bugs. Some users also report that PearPCCP removes comments from configuration files, while PearGUI does not. The PearPC.net website also released its own Java-based PearPC-GUI, called APE, which is part of the PearPC.net Package. CherryOS is alleged to be simply a front-end for PearPC. Its website was shut down in May 2005.[citation needed]
CherryOS controversy[edit]
Within five months of PearPC's release, another PowerPC emulator called CherryOS appeared, claiming to offer more features and greater speed. However, within hours of its announcement, questions were raised about the claims, with many experts and open-source advocates suggesting that CherryOS was nothing more than a repackaging of PearPC. The CherryOS Emulator was re-released in March 2005 as a commercial product. According to Cassondra Foesch, a principal author of PearPC, it still contained all or part of the code written for the PearPC Project. CherryOS also created questions regarding the legality of commercial software developed and marketed specifically for the purpose of running Mac OS on the x86 architecture, since Apple's license agreement specifically states that the operating system may only be installed on Apple-labeled computers. Eventually, the distribution of CherryOS ceased due to the very high amount of criticism that had been directed at it.[citation needed]
In addition, although CherryOS supports native CD-ROM installation, the emulator itself runs a bit slower than PearPC does, even though it claims to run three times faster than PearPC.[citation needed]

I admit it, I’m always with a lot of applications opened, Chrome with at least 6 tabs, Skype, Slack, PHPStorm or SublimeText, Airmail or Outlook for Mac, Photoshop and terminal.
I regularly login via SSH to VPS in Digital Ocean and AWS EC2 and then run some commands like:
Then I go to the wordpress site and start adjusting the settings, but by the time I get back to the terminal (5 – 10 minutes), the SSH session is frozen, so I’m forced to open a new one. I honestly became tired of this, and I remembered that SSH was built on TCP and as such it should have some “Keep Alive” settings like on SIP (sorry I come from the call center world). And after some search online, I found that you can make this change both from the server side (SSHD: Secure SHell Daemon) or from your CLI (*nix, Linux & Mac).
Reduce SSH Timeouts from the server
Reduce SSH Timeouts from your computer
All you need to do is to setup your ssh client to send a “Keep Alive” signal to the server every certain amount of seconds. So you can add the following text to your ~/.ssh/config
file:
This basically tells your computer to send “keep alive” signals to remote-host.com every 120 seconds (2 minutes). That way the session will not get frozen for that server.
If you want to enable this for all of the hosts that you connect to, then simply add the following strings instead:
This will setup the “keep alive” signal interval to 2 minutes for any host that you connect to via SSH.
After you finish editing the file, please make sure to change the permissions on the file using the following command:
It Alive Mac Os 11
And there you go, as simple as that! No more timeouts on my terminal app on my Mac OS El capitan MBP!
