A system that Apple already tested during the beta of iOS 16.4 and that now takes care of the security of operating systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A new way to update our devices<\/h2>\n\n\n\n<p>Unlike a conventional update, where it is much of the system that has to be reinstalled, even if it is to make relatively small changes, in this update what Apple uses is what <strong>is called Delta Update<\/strong>. A reference to the highly specialized Delta combat forces with a single objective that they accomplish without drawing attention to themselves.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Privacy on iPhone | A Day in the Life of an Average Person\u2019s Data | Apple\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/1HWUjMjaBJI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Similarly, these updates only modify some components of the system to improve its security without the need for a complete installation. And this is critical, because in addition to the download being minimal both in terms of weight and time, <strong>the update is as fast as a reboot<\/strong>.<\/p>\n\n\n\n<p>This can be read in two ways. The first is that we will be able to install the update with little or no interruption to our use of the devices. The second is that if we restart the iPhone, iPad or Mac, the update is installed, which is a great advantage for keeping them secure, even for those users who are not in the habit of manually installing updates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to install new security updates<\/h2>\n\n\n\n<p>To install the Security Response updates on our iPhone, iPad or Mac, <strong>the steps to follow are the same as for any other update<\/strong>. Specifically we will do it like this:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>We open the <em>Settings<\/em> app on our iPhone, iPad or Mac.<\/li><li>Go to <em>General<\/em>.<\/li><li>Tap on <em>Software Update<\/em>.<\/li><li>Once the update appears, tap on <em>Download and install<\/em>.<\/li><li>Our iPhone, iPad or Mac will restart as it would normally do.<\/li><\/ol>\n\n\n\n<div class=\"wp-block-image aligncenter size-full\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"374\" height=\"720\" src=\"https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2023\/05\/martes-02-may-2023-090829.png\" alt=\"\" class=\"wp-image-226905\" srcset=\"https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2023\/05\/martes-02-may-2023-090829.png 374w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2023\/05\/martes-02-may-2023-090829-156x300.png 156w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2023\/05\/martes-02-may-2023-090829-6x12.png 6w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2023\/05\/martes-02-may-2023-090829-150x289.png 150w\" sizes=\"auto, (max-width: 374px) 100vw, 374px\" \/><\/figure><\/div>\n\n\n\n<p>Meanwhile, if we want to know if the update has already been installed without us noticing it, the best thing to do is to <strong>check the version of the operating system that we have installed on our devices<\/strong>. On our iPhone or iPad we will do it like this:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>We open the <em>Settings<\/em> app on our iPhone, iPad or Mac.<\/li><li>Go to <em>General<\/em>.<\/li><li>Tap on <em>Information<\/em>.<\/li><li>Check that the <em>iOS\/iPadOS version<\/em> shows the number 16.4.1 (a).<\/li><\/ol>\n\n\n\n<p>On the Mac we will do something similar. In the Apple menu, we will choose <em>About this Mac<\/em>. Then, at the bottom, next to macOS, we make sure that &#8220;13.3.1 (a)&#8221; appears, which indicates that we already have the update.<\/p>\n\n\n\n<p>Right now, we do not know exactly what security improvements Apple has implemented in this quick update. Hopefully in the next few hours the company will update its support document with a list of the changes.<\/p>\n\n\n\n<p>In any case, if we see it appear on our device, since Apple is <a href=\"https:\/\/twitter.com\/aaronp613\/status\/1653098576929513491\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">deploying it progressively<\/a> and the process will take up to 48 hours, it is best that we install it as soon as possible. An update, remember, that is <strong>only available for devices already running the latest versions of iOS, iPadOS and macOS<\/strong> and that, as we have just seen, we can install in just a few seconds. While we wait for <a href=\"https:\/\/en.softonic.com\/articles\/ipad-os-17-stage-manager-presonalizationicon-leaks\" target=\"_blank\" rel=\"noreferrer noopener\">iPadOS 17 and its leaks<\/a>, clearly good news for our security.<\/p>\n\n\n<div class=\"sc-card-program\">\r\n  <div class=\"sc-card-program__body\">\r\n    <div class=\"sc-card-program__row clearfix\">\r\n      <div class=\"sc-card-program__col-logo\">\r\n        <img decoding=\"async\" class=\"sc-card-program__img\" alt=\"Freeform\" src=\"https:\/\/images.sftcdn.net\/images\/t_app-icon-m\/p\/933e1ce5-2062-40e7-8619-6978c3fdce16\/1997379573\/freeform-logo\" width=\"100px\" height=\"100px\">\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-title\">\r\n        <span class=\"sc-card-program__title\">Freeform<\/span>\r\n        <a class=\"sc-card-program__button sc-card-program-internal\" href=\"https:\/\/freeform.en.softonic.com\/iphone\" target=\"_self\" rel=\"noopener noreferrer\">DOWNLOAD<\/a>\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-rating\">\r\n        <svg class=\"rating-score__content\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" version=\"1.1\" x=\"0\" y=\"0\" viewbox=\"0 0 50 50\" enable-background=\"new 0 0 50 50\" xml:space=\"preserve\"><path class=\"rating-score__background rating-score--good\" fill=\"none\" stroke-width=\"6\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><path class=\"rating-score__value rating-score__value--0\" fill=\"none\" stroke-width=\"6\" stroke-dashoffset=\"0\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><text class=\"rating-score__number\" content=\"\" text-anchor=\"middle\" transform=\"matrix(1 0 0 1 25 31.0837)\" data-auto=\"app-user-score\"><\/text><\/svg>\r\n      <\/div>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <span class=\"sc-card-program__description\"><\/span>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <img decoding=\"async\" class=\"sc-card-program__bigpic\" src=\"\" onerror=\"this.style.display='none'\">\r\n    <\/div>\r\n    <a class=\"sc-card-program__link track-link sc-card-program-internal\" href=\"https:\/\/freeform.en.softonic.com\/iphone\" target=\"_self\" rel=\"noopener noreferrer\"><\/a>\r\n  <\/div>\r\n<\/div>\n\n\n\n<p><em>Some of the links added in the article are part of affiliate campaigns and may represent benefits for Softonic.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An update, let&#8217;s remember, that is only available for devices that already run the latest versions of iOS, iPadOS and macOS and that we can install in just a few seconds.<\/p>\n","protected":false},"author":9262,"featured_media":226902,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","wpcf-pageviews":0},"categories":[1015],"tags":[3817,3808],"usertag":[],"vertical":[],"content-category":[],"class_list":["post-226899","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-ios-16","tag-seguridad"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/posts\/226899","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/users\/9262"}],"replies":[{"embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/comments?post=226899"}],"version-history":[{"count":1,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/posts\/226899\/revisions"}],"predecessor-version":[{"id":320631,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/posts\/226899\/revisions\/320631"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/media\/226902"}],"wp:attachment":[{"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/media?parent=226899"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/categories?post=226899"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/tags?post=226899"},{"taxonomy":"usertag","embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/usertag?post=226899"},{"taxonomy":"vertical","embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/vertical?post=226899"},{"taxonomy":"content-category","embeddable":true,"href":"https:\/\/cms-articles.softonic.io\/en\/wp-json\/wp\/v2\/content-category?post=226899"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
