高三那年秋天，姑姑给我买了第一台笔记本电脑。全新的MacBook Pro，我简直不敢相信。事实证明，这台计算机在将近 10 年后仍在运行。但它的运行效率是否一样？带着一点温柔、爱和关怀，答案已被证明是肯定(YES)的。
升级旧MacBook Pro似乎是一项艰巨的任务，但它可以分为两类：软件优化和硬件升级。本文将重点介绍软件优化，我们将在另一篇文章中介绍硬件升级。
需要注意的是，如果您使用的是较旧的MacBook ，则不(NOT)应将操作系统更新为Mojave，因为有许多程序会遇到兼容性和索引问题。在大多数情况下，你甚至不会被允许。
这 7 个简单的任务将显着提高MacBook Pro的速度和存储空间。让我们开始吧。
6. 限制启动程序(6. Limiting Startup Programs)
通常，较旧的 MacBook 可能需要更长时间才能启动的最常见原因是机器首次开机时在后台运行的启动程序太多。这是一个简单的修复，您需要做的就是：
- 进入系统偏好设置(System Preferences)
- 单击用户和组(Users & Groups)
- 单击登录项(Login Items)选项卡
如果您在“登录项目(Login Items)”选项卡中看到启动时未启动的任何内容，只需单击该项目并单击右下角的减号 (-)(minus sign (-))，即登录时隐藏应用程序，选择应用程序旁边的隐藏列中的复选框(To hide an application when you log in, select the checkbox in the Hide column next to the application)。禁止应用程序在启动时启动已经大大加快了我的启动时间，它也适用于你。
5. 清理桌面(5. Clear Your Desktop)
您可能不会立即想到的一个简单修复方法是清除所有占用桌面(Desktop)空间的项目。如果有太多项目和文件夹，将所有这些文件夹和文件合并到一个文件夹中可能是值得的，您可以将其定向到桌面以外的某个位置。
我曾经将文件分散在我的桌面上，甚至将它们合并到 7 个文件夹中，极大地提高了我的启动和运行速度。
4.删除大文件(4. Deleting Large Files)
另一个众所周知的诅咒旧款MacBook的大问题是一个相当明显的问题：大型不需要的文件会显着降低旧款机器的性能。
通常，为了确保烦人的“死亡海滩球”留在它的网络笼子里，您需要确保至少 20% 的硬盘驱动器是空闲的。要释放空间，您只需：
- 点击屏幕左上角的Apple标志(Apple)
- 选择关于本机(About This Mac)
- 导航到存储(Storage)（第三个选项卡）并单击管理(Manage)
- 从这里您应该看到最大的文件并相应地删除它们。
如果您运行的是OS X 10.11 ( El Capitan ) 或更早版本，很遗憾，您将没有“管理(Manage )”按钮。在这种情况下，打开Finder，单击左侧栏中的所有我的文件，然后按大小(Size)列排序。
需要注意的重要一点是，左侧的iOS 文件是在 iCloud 以现在的方式工作之前创建的。(iOS Files)它是旧手机或 iOS 设备的精确副本，如果您启用了 iCloud，您应该将其删除，因为 iCloud 现在可以远程完成所有这些操作。
提及iTunes也很重要，因为旧电影或播客会占用大量空间，因此如果您已经看过这些电影，您可能需要考虑在之后删除它们。完成此操作后，我从硬盘驱动器中释放了大约 30 个演出。沙滩上的死亡之球不见了。
3.清除缓存(3. Clear the Cache)
清除系统缓存是我有一段时间没有做过的事情，它有助于加快速度。要清除系统缓存，您只需：
- 导航到Finder
- 从屏幕左上角的Go选项卡中，选择下拉菜单底部的Go to Folder
- 要进入缓存目录，请准确输入“~/Library/Caches”（不带引号）
- 删除Caches
文件夹中的所有内容。计算机需要的任何文件都会自动重新下载，因此您不必担心删除重要内容。
完成此操作后，您应该重新启动计算机，如果您之前没有清除缓存，您会注意到一个巨大的变化。
2.禁用文件保险箱(2. Disable FileVault )
在我见过的所有加速旧款MacBook Pro的技巧中，这个对我来说是最重要的改变。FileVault是OSX内置的加密功能，可加密您计算机上的所有文件和数据。
如果您不是需要大量安全性的知名人士（如我），则无需启用FileVault 。要禁用此功能，您需要：
- 导航到系统偏好设置(System Preferences)
- 选择安全和隐私(Security & Privacy)
- 选择选项卡FileVault
- 单击窗口左下方的锁定(Lock)图片以允许对此设置进行更改并输入您的管理员密码进行确认。
- 选择关闭 FileVault...(Turn Off FileVault…)
此过程的重要说明：
解密您的信息需要很长时间，因此当您在很长一段时间内不需要笔记本电脑时，这样做很重要。我建议在睡前这样做，因为众所周知这需要 4 到 12 小时。
这个技巧对我来说是最重要的改变，因为解密的数据需要更少的时间来加载。禁用它还为我腾出了 90.2 GB 的空间，所以我完全推荐它。
1. 重置 SMC 和 NVRAM(1. Reset SMC and NVRAM)
改善和升级MacBook性能的另一个非常有效的方法是重置SMC和NVRAM。SMC或系统管理控制器(System Management Controller)负责电池管理、热管理和更多硬件管理服务。
重置它可能有助于解决您可能遇到的过热或电池问题。根据Apple(Apple)支持， NVRAM或非易失性随机存取存储器是“ (NVRAM)Mac用来存储某些设置并快速访问它们的少量内存”。重置它对我来说非常有价值，因为我的硬盘已分区并且NVRAM会操纵启动磁盘设置。
您的MacBook设置可能与我的不同，您的重置选项也是如此。
要重置 SMC(To
reset SMC )，您只需：
- 转到此(this l)链接(i)并(nk)找到您的特定机器的重置选项
要重置 NVRAM(To
reset NVRAM)，您只需：
- 转到此链接(this link)并找到您的特定机器的重置选项
这些是您可以在OS X的用户界面中进行的优化。我希望这可以帮助大家延长您心爱的 MacBook 的使用寿命！对于硬件升级，请务必查看我的下一篇文章，我们将更换机器的内部组件以加快速度。如果您有任何问题，请随时给我留言，我会尽快回复您！
Upgrading a MacBook that’s Over 10 Years Old
It was the fall of my junior year in high schoоl when my aunt bought me mу first laptop. A brand-nеw MaсBook Pro and I absolutely сouldn’t believe it. As it turns out, this same computer is still running almost 10 years later; but is it running as efficiently? Wіth a littlе tenderness, love, and care the answer has proven to be YES.
Upgrading an old MacBook Pro may seem like a monumental task, but it can be split up into two categories: software optimizations and hardware upgrades. This article will focus on software optimizations and we will cover hardware upgrades in another article.
It’s important to note, if you have an older MacBook you should NOT update the operating system to Mojave, there are many programs that run into compatibility and indexing issues. In most cases, you won’t even be allowed to.
These 7 simple tasks will significantly improve the speed and storage space on your MacBook Pro. Let’s get into it.
6. Limiting Startup Programs
Oftentimes, the most common reason an older MacBook might take longer to boot up is that there are too many startup programs running in the background when the machine is first powered on. This is a simple fix and all you’ll need to do is this:
- Make your way to System Preferences
- Click on Users & Groups
- Click on the Login Items tab
If you see anything in the Login Items tab that you don’t what booted on launch, just click on that item and click the minus sign (-) at the bottom right under where it says To hide an application when you log in, select the checkbox in the Hide column next to the application. Disabling apps from starting on bootup has sped up my boot-up time dramatically and it will for you as well.
5. Clear Your Desktop
A simple fix that you might not think of right away is clearing all of the items that are taking up space on your Desktop. If there are too many items and folders it might be worth it to consolidate all of those folders and files into a single folder that you can direct somewhere besides your desktop.
I used to have files scattered all over my desktop and even consolidating them to 7 folders dramatically improves my bootup and runtime speeds.
4. Deleting Large Files
Another huge problem that’s been known to curse the older MacBook is a rather obvious one: large unwanted files significantly slow down the performance of an older machine.
Usually, to make sure that annoying ‘beach ball of death’ stays in its cyber cage, you’re going to want to make sure at least 20% of your hard drive is free. To free up space you simply need to:
- Click on the Apple logo at the top left of your screen
- Select About This Mac
- Navigate to Storage (the third tab) and click Manage
- From here you should see the largest files and delete them accordingly.
If you are running OS X 10.11 (El Capitan) or earlier, you will not have the Manage button, unfortunately. In this case, open Finder, click on All My Files in the left sidebar and then sort by the Size column.
An important thing to note, iOS Files on the left were created before iCloud worked the way it does now. It’s an exact copy of an older phone or iOS device, which you should delete if you have iCloud enabled because iCloud does all of that remotely now.
It’s also important to mention iTunes because old movies or podcasts will take up a significant amount of space, so if you’ve already seen these movies you might want to consider deleting them afterward. After doing this I freed up approximately 30 gigs from my hard drive. The ‘beach ball of death is gone.
3. Clear the Cache
Clearing the system cache is something that I haven’t done in a while and it helped speed things up. To clear the system cache, you simply need to:
- Navigate your way to Finder
- From the Go tab at the top left
hand of the screen select Go to Folder at the bottom of the dropdown
menu
- To make your way to the caches directory,
type this in exactly “~/Library/Caches” (without the quotation marks)
- Delete everything inside of the Caches
folder. Any file that the computer needs will automatically be redownloaded, so
you don’t have to worry about deleting something important.
After doing this you should restart your computer and you’ll notice a dramatic change if you haven’t cleared the cache before.
2. Disable FileVault
Out of all of the tips I’ve seen for speeding up an older MacBook Pro, this one made the most significant change for me. FileVault is the OSX built-in encryption feature that encrypts all of your files and data on your computer.
If you’re not a high-profile individual that needs a ton of security (like me), you will not need to have FileVault enabled. To disable this feature, you will need to:
- Navigate to System Preferences
- Select Security & Privacy
- Choose the tab FileVault
- Click on the Lock picture at the
bottom left of your window to allow changes to be made to this setting and type
in your administrator password to confirm.
- Select Turn Off FileVault…
An important note for this process:
Decrypting your information will take a LONG time, so it’s important you do this when you won’t need your laptop for a significant amount of time. I would recommend doing this before bed because it’s been known to take anywhere between 4 and 12 hours.
This tip made the most significant change for me because the decrypted data takes way less time to load. Disabling this also managed to free up 90.2 gigabytes of space for me so I completely recommend it.
1. Reset SMC and NVRAM
Another very impactful method for improving and upgrading MacBook performance is resetting the SMC and NVRAM. SMC or System Management Controller is responsible for battery management, thermal management, and many more hardware management services.
Resetting this might help solve overheating or battery issues you might be experiencing. NVRAM or nonvolatile random-access memory is, “the small amount of memory that your Mac uses to store certain settings and access them quickly” according to Apple support. Resetting this was incredibly valuable for me because my hard drive is partitioned and NVRAM manipulates startup disk settings.
Your MacBook setup will probably be different than mine, so will your reset options.
To
reset SMC you simply need to:
- Go to this link and find the reset options for your specific machine
To
reset NVRAM you will simply need to:
- Go to this link and find the reset options for your specific machine
These are the optimizations you can do within the user interface of OS X. I hope this helps you all extend the lifespan of your beloved MacBook! For hardware upgrades, be sure to check out my next article, we’re going to be replacing internal components of the machine to speed it up. If you have any questions, feel free to message me and I’ll get back to you as soon as possible!
