"The start of Mac is slow recently. How do you do it?"This is a question that I often ask for 30 years of MAC user history.When I purchased it, it was so fast, but if I continued to use a Mac, the startup gradually became slow.Everyone will experience it once.But please be assured.There are various causes of slow, but if you know the right technique, you can solve it yourself.However, it is important to note that there are incorrect methods on the Internet, and there are some Macs equipped with M1 chips that adopt new architectures.Here, we will explain the latest techniques related to speeding up Mac startup.
Speed of Mac ... but before that
If you think that Mac is slow, you may want to search for keywords such as "Mac Large Reasons" and "Mac Fast Speed" with search engines such as Google.Many search results will be displayed, and various articles will be hit.However, it should be noted that some of the measures described in such articles are effective, but they are not currently used or have the opposite effect.There is also a way to twist your neck as an affiliate purpose.Therefore, here, I would like to organize the correct speed -up method that is valid in the case of Mac "slow".
First of all, there are three high -speed techniques that can be easily tested: (1) "restart", "organize the starting items", and (3) update MacOS and apps to the latest version.Restarting can resolve the causes of slowness by ensuring a defective application or process, and minimizes the starting items that are automatically loaded as soon as you log in.You can shorten the time to start up.Also, it is important to keep the OS and apps in the latest version, as the software may have some problems with the launch of the Mac.None of them takes time, so if you feel that Mac is slow, try it as soon as possible.

The next easy to do is "secure free space for SSD and HDD".If the built -in storage capacity of the Mac is small, the speed of use will be slower as well as the Mac startup (it will be directly linked to the product life).Storage consumption by regularly enabling the function of emptying trash cans, using the storage optimization functions that are standard on MacOS, and migrating data to cloud services such as iCloud and external storage.Let's reduce.As a guide, at least 10 to 20%of the storage wants to secure free space.
SSDの空き容量の少なさは、Macの起動はもちろんすべての性能に悪影響をおよぼします。Appleメニューの[このMacについて]→[ストレージ]タブから自分のMacの状況を確認しましょう[ストレージ]タブの右上にある[管理]をクリックすると、macOSに標準搭載されている各種ストレージ管理機能を利用できますIn addition, a simple method that is surprisingly overlooked is ⑤ "Start in safe mode".The Safe mode, which boots the Mac while holding down the [Shift] key, verify the startup disk and repair the directory problem as needed, delete font cache, kernel cache, and other system cache files., While using a Mac, it helps to solve the natural problems.
Intel Macでセーフモードを有効にするには、電源を切った状態から[Shift]キーを押したまま電源ボタンを押し(コールドスタート)、ログインウィンドウが表示されたら指を離します。画面の右上に「セーフモード」と表示されていればOKですIn addition, it is worth trying "resetting SMC and NVRAM/Pram".SMC (system management controller) is a controller that mainly manages functions such as power supply, various sensors, and note -type Macs, such as batteries and keyboard backlights.On the other hand, NVRAM (non -volatile random memory) or PRAM (parameter RAM) writes the volume, screen resolution, startup disk, time, etc. in a small memory that can be stored when power is turned off, and reads the settings at startup.Quickly reflect the settings when logging in the Mac.If you have any problems or performance deterioration due to problems, resetting will be effective.
Apple T2プロセッサ搭載の有無などモデルによってSMCのリセット方法は異なりますが、Intel Macでは電源ボタンの長押しやキーコンビネーションによってリセットできますIntel Macでは、起動時に[command]+[option]+[P]+[R]キーの同時押しでNVRAM/PRAMをリセットできます。ファームウェアパスワードを設定してある場合は「macOS復旧」で無効にしておきますHowever, it is important to note that the situation is different between the Mac (Intel Mac) equipped with the Intel CPU and the Mac (hereinafter M1 Mac) equipped with an M1 chip developed by Apple.To start the M1 Mac in safe mode, use the "Startup Manager" which is displayed when the power button is pressed for about 10 seconds.On the other hand, "resetting SMC and NVRAM/Pram" could be performed by long pressing and key combination of the power button on Intel Mac, but the M1 Mac has been abolished because the system startup process has changed.
M1 Macでは起動時に電源ボタンを長押しすると「スタートアップマネージャ」が表示され、ここから起動ボリュームの選択や「macOS復元」、セーフモードでの起動などMacのメンテナンスに必要な機能を呼び出せますEffective clean installation
So far, we have introduced techniques that users can do relatively easily, but if they still do not improve, it will be a little troublesome, but let's try "MacOS reinstall".If you are using a Mac, you may not know that there is an unnecessary data called a cache inside, or the OS may cause malfunction due to some reason, which causes slowness.It is possible.It may be troublesome to hear "MacOS reinstallation", but Mac can reinstall only the OS with data and settings.Although it takes time to reinstall, you can use a Mac without having to re -set up.
If the OS is reinstalled, it is a last resort, "MacOS Clean Installation".Since all data and settings in the Mac will be deleted and initialized, after installation, you will need to re -set up the data and settings you have used so far, but you will start using the Mac from the factory shipping state.You can expect the maximum effect because it will be (it goes without saying in the case of MacOS clean installation, but even if you reinstall MacOS, be sure to back up Mac data before execution in preparation for some trouble.I need).If the symptoms are still not improved, it may be a Mac hardware problem or the Mac is old in the first place, so it is better to consider replacing the machine.
Intel製CPUを搭載したMacの場合は、Macを再起動してグレーの画面が表示されたらすぐに[command]キーと[R]キーを同時に押します。「macOSユーティリティ」が表示されるので「macOSを再インストール」をクリックして、以降は指示どおりしたがって行けばmacOSの再インストールが行なえますmacOSのクリーンインストールは、macOSユーティリティ画面から「ディスクユーティリティ」で起動ボリュームを選択して消去し、「APFS」でフォーマットします。その後「macOSを再インストール」で工場出荷時に戻ります。ただし、ユーザーデータが完全に削除されること、事前に「Macを探す」を解除しておくなど注意が必要です"Wrong" high -speed technique that cannot be expected
In addition, as a high -speed method seen on the Internet, ⑨ "repair access rights with" disk utility "", "Use memory release software", ⑪ "Use anti -virus software and utility tools", and "Dark"."Disabling visual effects such as mode" and ⑬ "Organize desktops".However, these were previously effective, but the current MacOS is not effective or not.
First, for the access right of system files, OS X El Capitan (10).11) After the macOS will be repaired automatically, there is no need to manually repair it using "Disk Utility".For the release of memory, OS X Mavericks (10).It is not effective after the installation of the "memory compression" function installed in 9).In both cases, articles are still posted on the Internet, but it is a method that does not lead to speeding up now.
In addition, some of the third -party apps claim to speed up the Mac, but some tools do not have Apple's notary.The current MacOS is not suitable for installation in the first place because the security technology "System consistency protection (SIP)" that protects Mac from malicious software is enabled by default.In addition, regarding visual effects off and desktop organizing, you will not be able to find any meaning other than psychological effects.
As we have seen so far, there are various ways to speed up the launch of a Mac, but which is effective depends on the user's environment.However, at least the technique of ① to ⑧ is not a wrong way, so if you feel it is slow!In order to prevent the launch of the Mac, regular maintenance, such as organizing login items, deleting unnecessary data, and deleting unnecessary software, is important.Be sure to know not only how to speed up in case of emergency, but also how to care for your daily Mac.
