I have audio recording file but the sound is too soft and light. MacBook, Mac OS X (10.6.8). You may refer to the following step by step guide on How to Increase Audio Volume in MP3, MP4, WAV, WMA, WMV, MKV, VOB, MPG? Increasing the volume on an audio or video file with our Mac computers. Tuning Mac OS X Performance. This FAQ provides recommendations for optimizing Mac® OS X performance. Additionally, it provides advice and links to advice for troubleshooting certain Mac OS X performance problems. (VM), which requires free disk space on your startup disk, aka your boot volume. If you startup disk is nearly full, your Mac's.
Just like people Macs are prone to slowing down the older they get, but after recently upgrading to OS X Lion some users are protesting their machines have aged before their time. Since the release of Lion back in July its been subject to a number of criticisms, while some of these may not be justified, it is difficult to ignore the growing chorus of of performance issues after upgrading. It is of course possible that Apple will fix some of these issues in a future update, however until then many users will search for ways to boost the performance of their machines. After researching and testing a wide range of suggestions and fixes I have compiled a list of what I think are the 17 best ways to speed up your Mac running Lion. Meet the minimum requirements It sounds obvious but check your system meets Lions minimum requirements. Lion requires a minimum of 2GB of RAM and a Mac with one of the following processors: Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor. 2GB of memory should be considered the absolute minimum, many people are finding that for Lion to roar you will need at least 4GB.
Clean install The majority of “upgraders” to Lion did so using the Mac App store which doesn’t provide the facility to do a clean install. If you are experiencing serious issues with Lion its highly recommended you try this step. To do a clean install of OS X Lion you will need to create (or buy) a bootable USB stick or DVD, see our step by step guide:. Repair Disk Permissions The usefulness of repairing disk permissions on the Mac has long been the subject of debate. It is often wrongly heralded as the solution to a wide variety of performance problems. However recently many people have reported that after upgrading to Lion repairing disk permissions cured a host of issues. Open Disk Utility in the Utilities Folder, select your startup disk then click Repair Disk Permissions.
It may be preferable to run Disk Utility in Recovery mode, Restart your Mac while holding the option key, then select Recovery HD and click the arrow. Select Disk Utility and repeat the above steps. Check Running Processes You may be running an application that isn’t optimised for Lion and causing your system issues. You can see what apps and processes are running on you Mac and their memory usage using Activity Monitor. You can find Activity monitor in your Utilities folder, fire it up to see which processess are using your systems resources. You can force quit individual processes by selecting them and clicking the “Quit Process” button.
Before you start quitting processes check out this great list of 5. Disable Auto-Resume One improvements brought to OS X with Lion is Auto Resume, a feature borrowed from iOS which enables applications to save their states automatically. This feature applies to all applications and the finder itself, while definitely welcome addition to the OS there is no doubt that on older machines could suffer from the extra burden. To disable open System Preferences and click “General” uncheck the “Restore windows when quitting and restoring apps” option. You can also use this keyboard shortcut to quit an app and discard its windows: ⌥⌘Q (alt + command + Q) 6. Check application compatibility Many users performance issues stem from software or utilities that are out of date or haven’t been optimised for Lion.
Check that your apps are compatible using this handy. Disable browser extensions For many web browsers are the most resource hungry applications they use. Aside from the obvious tips like clearing the cache and closing unused tabs, extension have been reported as causing slow downs with Lion (AdBlock in Safari being the cause of one commenters pain). Try disabling them to see if they are the thorn in your Lions paw. To disable extensions in Safari: Launch Safari, open “Preferences” under the main “Safari” menu then choose “Extensions”.
Select the extension in the left hand column that you wish to disable then click the Uninstall button in the main window. To disable extensions in Chrome: Launch Chrome, open “Extensions” under the “Window” menu.
Uncheck “enabled” beside the extensions you want to disable. To disable extensions in Firefox: Launch Firefox, open “Add-ons” under the “Tools” menu. Choose “Extensions” in the left hand column. Stay Organised With the introduction of full screen apps and Mission Control in Lion, its easier than ever for your mac to get bogged down with unused spaces, windows and apps. Stay organised and streamlined by closing unused applications, windows and spaces. To close/combine spaces launch Mission Control and hover the cursor over a desktop at the top of the screen, after a slight delay a close icon will appear.
Turn off unnecessary Login items Login items can be handy but they do effect boot up times and often costume resources while unused. This can become even more of a problem if you have Auto resume enabled. To turn off Login items.
Open System Preferences, click “Users & Groups” then choose the “Login items” tab. Simply select the apps you no longer want to open on login and remove them with the “minus” (-) button. Force Spotlight to Re-index Spotlight automatically indexes the contents of your Mac in the early hours each morning. But if you turn your Mac off at night Spotlight may not have had a chance to reindex. While unlikely to cause major performance problems it could cause unresponsiveness and issues while using spotlight.
To force Spotlight to reindex, open System Preferences, click “Spotlight” then choose the “Privacy” tab. Click the “+” icon and choose the volume you want to reindex. After a few minutes remove the volume using the “-” icon.
Spotlight will reindex the volume. RAM The role of Ram in system performance really cannot be overstated. If your Mac is upgradable and you can afford it increasing your Ram is the single biggest thing you can do to speed up Lion. It doesn’t cost the earth either: for a 2011 iMac you can get a 8GB Kit (4GBx2) for less than fifty bucks. Reclaim Hard Disk Space When your Hard Drive gets close to its capacity (in excess of 90% full) system performance can dip considerably. OS X cleverly uses your Hard Disk as Virtual memory it can use in addition to your actual Ram.
A full hard disk and insufficient Ram is the recipe for an extremely lethargic Mac. But before you start ruthlessly culling your music library of Barry Manilow and ABBA albums you could try a few of the space saving tips below. Remove the unnecessary language files and resources bundled with OS X by downloading. This should recover up to half a gigabyte of disk space.
Upgrade to an SSD Anyone familiar with using one of the latest generation of Macbook Airs will attest to the massive speed benefits of SSDs. Despite the constraints of the Airs limited Ram and Processor it still achieves blistering start up times of under 15 seconds. SSDs improve system performance radically because data can be retrieved SSDs are available as an extra on most new Macs but if you are willing to get you hands dirty and void your warranty you may be able to upgrade you old Mac.
Preferences Preference files can become corrupt and can cause programs to crash or run slowly. Deleting these files will cause them to be recreated once the application they are associated with is relaunched. Preference files are located here: Macintosh HD / Library / Preferences. To remove or disable unused System Preference Panes which can also be detrimental to system performance see:. Caches, log files & temporary items Regularly clear out built up caches and log files to save disk space and keep your system lean. Eye Candy OS X has always had more than its fair share of animations and lighting effects. However Lion takes this to a new level incorporating iOS style effects and skeuomorphic UI Textures.
While its certainly arguable that the performance increase gained from removing Lions animations is slight, the time saved from these effects “playing out” adds up and makes your Mac feel more responsive. Disable window animations in the terminal by typing: defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool NO Press Enter then relaunch the Finder with the Force Quit Applications function (press cmd+alt+esc). To enable again repeat but replace the NO at the end of the terminal command with YES Disable Mail reply animations in the terminal by typing: defaults write com.apple.Mail DisableReplyAnimations -bool YES Press Enter and relaunch Mail. To enable again repeat but replace the NO at the end of the terminal command with YES Disable the switching Spaces animation in the terminal by typing: defaults write com.apple.dock workspaces-swoosh-animation-off -bool YES && killall Dock To enable again, type the following: defaults delete com.apple.dock workspaces-swoosh-animation-off && killall Dock 17. TinkerTool If you are not comfortable playing around in the Terminal then I suggest you check out. TinkerTool has a simple interface that allows you to easily tweak system settings by just checking or unchecking boxes, rather than entering lengthy terminal commands.
TinkerTools gives you access to a wide array of extra preferences that have been built into OS X. You can use Tinkertool to simply turn off Animations for opening apps and files, deactivate the Dashboard and turn off font smoothing and Dock transparencies.

Kodi runs well on what are relatively 'underpowered' systems, thanks to hardware video decoding being common on nearly all supported platforms. These requirements don't include what might be required for some 'advanced' features, such as PVR, which might require additional hardware. (formerly called ) first ported XBMC Media Center software to Mac OS X in 2008, and the whole project cross-platform application was renamed to Kodi in 2014. Kodi itself is a huge open source project and it takes loads of people working together to maintain it for all platforms, that is why is always on the lookout for C/C programmers to volunteer in assisting us with the development of Kodi.

Kodi v17 requires Mac OS X 10.8 or later. Kodi v18 (and its nightlies) will at least require 10.9). All hardware requirements are the same as those for OS X 10.8.
If your computer can run OS X 10.8 or later then your hardware should work just fine with Kodi. 3 How-tos Network File System, or, is a way to share folders over a network, and was added to XBMC in v11 (Eden). The main benefits of using NFS instead of SMB are its low protocol overhead (which allows it to send data across a network more quickly) and its use of simple to authenticate users rather than username/password combinations. This part bears repeating, as many people are confused on this point and try to create usernames and passwords to get Kodi to work with NFS: NFS does not use usernames or passwords as logins; it uses a UNIX-based 'userID' (UID) alone. This page describes how to share media files using the SMB/CIFS protocol, also known as Windows file sharing, that are on a computer running Mac OS X. When the media files are shared on your network you can then access those files using any other version of Kodi, even if it uses another OS.
